This all depends on the element's atomic number (number of protons). Since atoms have the same number of protons as they do electrons, the atomic number is essentially equal to the number of electrons as well. For example Aluminum atomic Th...

For example, when you go across the table from carbon to nitrogen to oxygen, the number of valence electrons increases from 4 to 5 to 6. As we go from fluorine to neon to sodium, the number of valence electrons increases from 7 to 8 and then drops down to 1 when we start the new period with sodium.

Many elements have several possible valences. ... For main group elements, the number of valence electrons is easy to determine: it equals the element's group number (a Roman numeral you'll find at the top of the column the element is in, on the periodic table).
