Bonding Intro and Ionic Formulas

SWBAT... …describe the formation of an ionic bond. 

Ionic bonds exist because...

• cations and anions attract.

• they are sharing electrons between ions.

• like charges attract.

• the difference in electronegativity is very small.

If the difference of electronegativity is smaller than 0.3, the bond is....

• ionic

• metallic

• polar covalent

• nonpolar covalent.

The difference of electronegativity between sulfur and oxygen is 1.0. Therefore, they form the following bond:

• ionic

• metallic

• polar covalent

• nonpolar covalent

Generally, a metal and a nonmetal form this type of bond:

• ionic

• metallic

• polar covalent

• nonpolar covalent

• ionic

• metallic

• covalent

• ionic and metallic
