Properties of ionic compounds
Form when electrons are transferred
Must have at least one atom wanting to give electrons (left side of PT) and one wanting to receive electrons (right side of PT)
Ionic bonds are formed between charged atoms (ions)
Form network structures, not molecules (form into large groups where each atom is attracted to all those around it)
Form solids at room temperature
Do not conduct electricity unless melted or dissolved
Begin covalent compounds
Form when electrons are shared
Form between atoms that want more electrons (right side of PT)
Form molecules (small groups)
Can be solid, liquid, or gas at room temperature
Do not conduct electricity
