Simply look at the periodic table. The number of valence electrons is the same as the group number. Ex: Boron has 3, Carbon has 4, Nitrogen has 5..

You can determine how many valence electrons an atom has by what family the element of the atom is in. For instance, if the element is in family 8A, the number of valence electrons will be 8. Or, if the element is in family 2A, the number of valence electrons for the atom will be 2. So, whatever number family the atom is in, the number of valence electrons equals that.
