Unit #5 COMPOUNDS

5.2 - Covalent Bonding (Revisited)

In section 4.7 we learned that covalent bonds are formed by the sharing of electrons between nonmetals. Specifically, when a covalent bond is formed between two identical nonmetals, a nonpolar covalent bond is formed.

When two or more atoms are joined together chemically by covalent bonds, a molecule is formed. The mass of a molecule is called the molecular mass.

Take a look at the kind of molecules that have this kind of bond again.

Point to consider:

What kind of bond would be formed if the sharing of electrons is between two different nonmetals?
