Ions & Ionic Bonding

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that involves the transfer of electrons from one atom to another, resulting in the attraction between oppositely charged ions.

Front

What happens to an atom that loses electrons?

Back

An atom that loses electrons becomes positively charged.

Front

What happens to an atom that gains electrons?

Back

An atom that gains electrons becomes negatively charged.

Front

What is the charge of an ion that has lost 2 electrons?

Back

The ion has a charge of +2.

Front

What is the charge of an ion that has gained 3 electrons?

Back

The ion has a charge of -3.

Front

What type of ions are attracted to each other in ionic bonding?

Back

Oppositely charged ions are attracted to each other in ionic bonding.

Front

What is a polyatomic ion?

Back

A polyatomic ion is a charged ion composed of two or more atoms bonded together.

Front

Give an example of a common ionic compound.

Back

Sodium chloride (NaCl) is a common ionic compound.

Front

What is the role of electrons in ionic bonding?

Back

Electrons are transferred from one atom to another to form ions that bond together.

Front

What is the difference between cations and anions?

Back

Cations are positively charged ions (lost electrons), while anions are negatively charged ions (gained electrons).
