What Makes Elements Different From Each Other?

The number of protons in an atom is the defining feature of an atom. It’s what makes one element different from another. The number of protons in an atom is called its atomic number. … All the elements in the universe are arranged according to their atomic number in the periodic table.

How do elements differ from each other quizlet?

What makes one element different from another? Elements are different because they contain different numbers of protons. … The number of neutrons in an atom is the difference between the mass number and the atomic number.

Why are all elements so different?

The difference in the number of protons and neutrons in atoms account for many of the different properties of elements. … They are the glue that holds atoms together in chemical bonds. The basic electron number is determined by the number of protons.

What defines an element and makes one element different from another element?

What makes one element different from another is the number of protons in the nucleus of its atoms. An atom is the smallest particle of an element that retains the properties of that element. Atoms contain protons and neutrons in the nucleus and electrons outside the nucleus.

Which elements typically have similar properties?

The periodic table shows the elements (C) in the same columns that typically have similar properties. These columns are called groups.

What are two ways that atoms of different elements are different?

Only if the number of protons (and consequently the electrons) is different the atoms are of two different elements. The number of neutrons in atoms of different elements can be the same and so can the number of neutrons in two atoms of the same element be different.

How are atoms of the same element similar and different?

ISOTOPES AND ATOMIC MASSES

See also what do we need to live

For many of the chemical elements there are several known isotopes. Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element they differ in the number of neutrons in the nucleus.

How are atoms and elements similar?

A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. … All isotopes of a particular element have the same number of protons but can have different numbers of neutrons.

Which elements typically have similar chemical and physical properties?

The answer is b. Elements in the same group have the same number of valence electrons and so interact with other elements in a similar way. They display similar physical and chemical properties. For example the halogens (F Cl Br I) all react similarly.

In what way are elements in the same row of the periodic table the same?

All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way groups of elements in the same column have similar chemical and physical properties reflecting the periodic law.

What is two or more elements chemically combined make up a?

Elements can be chemically combined into compounds therefore a compound consists of two or more elements combined in definite proportions by chemical means. Compounds may be formed by combining atoms of their constituent elements by ionic bonds or by covalent bonds.

Why are 2 elements different?

Two atoms of the same element can be different if their electrons are in different states. If one copper atom has an electron in an excited state and another copper atom has all of its electrons in the ground state then the two atoms are different.

How are two elements of the same element alike?

Different isotopes of the same element have the same atomic number. They have the same number of protons. So we conclude from above that two atoms of an element are alike because in an atom of a given element its atomic number remains the same.

What is differences in terms of elements?

Element. The difference between an element and a compound is that an element is a substance made of same type of atoms whereas a compound is made of different elements in definite proportions. … Examples of elements include iron copper hydrogen and oxygen.

How do you know if elements are similar?

Two different elements have similar chemical properties when they have the same number of valence electrons in their outermost energy level. Elements in the same column of the Periodic Table have similar chemical properties.

Why do elements in the same group have similar properties?

In chemistry a group is a vertical column in the periodic table of the chemical elements. … Each element within a group has similar physical or chemical properties because of its atom’s outermost electron shell (most chemical properties are dominated by the orbital location of the outermost electron).

What three elements are likely to have similar chemical and physical?

Question: Which three elements are likely to have similar chemical and physical properties? – boron silicon and germanium.

What elements have the most similar chemical properties?

The elements that have the most similar chemical properties are those in the same group or column of the periodic table.

Why is each element unique and different from other elements in chemical properties?

Each element is unique and different from other elements because of the number of protons in the nuclei of its atoms. … Different atomic forms of an element contain the number of protons but a different number of neutrons.

What do elements in the same group have in common What do elements in the same period have in common?

Elements in the same period are those that are in a single horizontal line from left to right. They do not share the same type of chemical reactivity as seen in groups. They only real thing that these elements share in common is the same principal quantum number or main energy shell.

What does it mean if elements are in the same group?

The elements in each group have the same number of valence electrons. As a result elements in the same group often display similar properties and reactivity.

What is an element What are the different types of elements?

Elements can be classified as metals metalloids and nonmetals or as a main-group elements transition metals and inner transition metals.

What determines the unique properties of an element?

Atomic Number and Mass

Each element has its own unique properties. Each contains a different number of protons and neutrons giving it its own atomic number and mass number. The atomic number of an element is equal to the number of protons that element contains.

When atoms of different elements combine what they form?

When two or more elements combine to form a new substance it is called a compound. There are many different types of compounds because atoms of elements combine in many different ways to form different compounds. Examples include water (H2O) and table salt (NaCl). The smallest part of a compound is a molecule.

What elements can be combined?

When two distinct elements are chemically combined—i.e. chemical bonds form between their atoms—the result is called a chemical compound. Most elements on Earth bond with other elements to form chemical compounds such as sodium (Na) and Chloride (Cl) which combine to form table salt (NaCl).

Who said atoms of different elements are different?

Scientist who contributed to the modern atomic theory.
Question Answer

What four elements are in all living things?

Carbon hydrogen oxygen and nitrogen are the most important elements. Small quantities of other elements are necessary for life. Carbon is the most abundant element in living matter.

Are atoms and elements the same thing?

An element is the simplest form of a substance. … An atom is the part of an element. A particular element is composed of only one type of atom. Atoms are further composed of subatomic particles called electrons protons and neutrons.

Are all atoms same?

They are not the same at all. Every atom consists of three basic units protons neutrons and electrons and these units determine the physical and chemical properties of an atom and matter. But the presence of a different number of these units( protons neutrons and electrons) makes an atom unique from the other atom.

Which elements have similar properties to each other and why?

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties.

Which pair of elements are the most similar?

Elements that are in the same group of the periodic table are most likely to exhibit similar chemical and physical properties. We therefore expect that Ca and Mg should be most alike because they are in the same group (group 2A the alkaline earth metals). Locate Na (sodium) and Br (bromine) on the periodic table.

How are periods and groups different from each other?

D. Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period.

What is similar about elements in the same period?

Elements in the same period have the same number of electron shells moving across a period (so progressing from group to group) elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.

Why do elements in the same family generally have similar properties provide one element as an example to support your reasoning?

Why do elements in the same family generally have similar properties? Choose one as an example to support your reasoning. Families/groups have similar properties because they have the same # of valence electrons. Alkali metals all have ONE valence electron “ns1” and react with water.
