2.3 Ionic Chemical Bonding TEST

Ionic bonds are normally formed when:

• Two metals share electrons.

• A metal and a non-metal exchange electrons.

• Two non-metals share electrons.

• A non-metal and a noble gas exchange electrons.

Covalent bonds are normally formed when:

• Two metals exchange electrons.

• A metal and a non-metal share electrons.

• Two non-metals share electrons.

• A non-metal and a noble gas exchange electrons.
