The number of valence electrons is given by the GROUP NUMBER which runs along the top of the periodic table. Oxygen, in group VIA, for example, has 6 valence electrons. Magnesium, in group IIA, has 2.

Group number will generally tell you how many valence electrons in the element. All of the elements in a single group will have an identical number of valence electrons. All of the Group 18 elements (noble gases) will have full outer main energy levels, thus no valence electrons. Transition metals will always have 2 valence electrons.
