Chemical Bonding

When cations lose electrons, they take on what charge?

• Positive

• Negative

• Neutral

• It will depend on what they bond with

Answer explanation

An easy way to remember this: Cats have paws, so CATions must be PAWSitive

When Anions gain electrons, they take on what type of charge?

Ionic Bonds (metals and non-metals) will apply prefixes when named. True or False

• True

• False

• Sulfur Oxide

• Sulfur Tetroxide

• Sulfate

• Sulfite

Answer explanation

This is a polyatomic ion. Polyatomic ions are covalently bonding ions that will act as one unit and cannot be separated.

• Dilithium monoxide

• Lithium dioxide

• Lithium oxide

• Lithate

Answer explanation

This is an ionic bond, a bond between a metal and a non-metal therefore the prefixes will not need to be applied.

• Dinitrogen Pentoxide

• Nitrate

• Nitrite

• Nitrogen Oxide

Answer explanation

This is a covalent bond which forms between two non-metals therefore prefixes must be applied when naming.

Which of the following is NOT one of the ten prefixes used for naming Covalent Compounds?

• Tetra

• Hepta

• Cinco

• Deca
