Describe covalent and ionic bonding?
covelant- bond in which one or more pairs of electrons are shared between two atoms.
ionic- bond in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other.

What is electronegativity?
This happens when an atom steals an electron from another atom, sometimes resulting in a balance change, by becoming positive or negative.  The lower the number the less electrons the atom will keep, the higher the number the more electrons the atom will try to take from the lower numbers. 

List the electronegativity values for H, Na, Cl, and O.
H-2.2
Na-0.93
Cl-3.16
O- 3.44
