Ionic and Covalent Bonding

Why do all bonds form?

• so the number of protons equals the number of electrons

• so an atom can become unstable

• to fill the outermost energy level

Valence electrons are found

• in the innermost energy level of an atom

• in the middle energy level of an atom

• in the outermost energy levels of an atom

Covalent bonds are between

• metal and non-metal

• non-metal and non-metal

• metal and metal

Ionic bonds are between

• metal and non-metal

• non-metal and non-metal

• metal and metal

Atoms are most stable when their outer shell is complete.

• True

• False
