# Covalent and Ionic Bonding

## Ionic Nomenclature

• Cation uses its original name (e.g. Sodium)
• If the anion has no extra oxygen (e.g. Cl, N, O, etc.), change suffix to -ide (e.g. Cl becomes Chloride)
• If the anion has standard number of oxygen (e.g. $$PO_4$$ ), change suffix to -ate (e.g. $$PO_4$$ becomes Phosphate)
• If the anion has one less than the standard number of oxygen (e.g. $$NO_2$$), change suffix to -ite (e.g. $$NO_2$$ becomes Nitrite)
• If the anion has two less than the standard number of oxygen (e.g. $$NO$$), change the prefix to hypo- and the suffix to -ite (e.g. $$NO$$ becomes Hyponitrite)
