An atom, or a group of atoms that has an electrical charge, either positive or negative.

• electron
• ion
• nucleus
• orbital

Metals lose electrons to form

• positive ions
• negative ions

Non-metals gain electrons to form

• positive ions
• negative ions

Formed when positively charged metal ions attract negatively charged non-metal ions.
