Front

What is an ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net electrical charge.

Front

What is a cation?

A cation is a positively charged ion that has more protons than electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion that has more electrons than protons.

Front

How does adding or removing neutrons affect an atom?

Back

Adding or removing neutrons changes the mass of the atom but does not affect its charge.

Front

How many electrons does a neutral atom have?

Back

A neutral atom has the same number of electrons as protons.

Front

What is the charge of a neutral atom?

Back

The charge of a neutral atom is zero.

Front

What happens to the number of electrons in an atom when it becomes a cation?

Back

When an atom becomes a cation, it loses one or more electrons.

Front

What happens to the number of electrons in an atom when it becomes an anion?

Back

When an atom becomes an anion, it gains one or more electrons.

Front

If a chlorine atom has 17 protons, how many electrons does it have?

Back

It has 17 electrons.
