<span>Solutes become electrolytes by ionizing. Ionic compounds therefore make good electrolytes; covalent compounds don't.</span>
The total number of elements that one particular element can bond to can be determined by simply drawing the Lewis structure of the element.
Place the chemical symbol
Then look at the group number = valence electrons
Distribute the valence electrons around the atom.
C = 4 bonds
N = 3 bonds
O = 2 bonds
