A substance made of two or more elements that have reacted together or that are chemically bonded together.

A unit of currency that supports Communism.

What happens to the electrons when ionic bonds are formed?

They are transferred - non-metal atoms gain them, and metal atoms lose them.

They are shared between the atoms.

Why do the elements in Group 1 form ions with a single positive charge?

Because they lose an outer-shell electron

Because they gain an outer-shell electron
