the period number tells which is the highest energy level occupied by the electrons
the period number tells which is the highest energy level occupied by the electrons
it very easy: whatever row the element is in is the number of energy levels it has. Example: hydrogen in the first row, it has 1 energy level.Read more: How_do_you_find_number_of_energy_levels_in_an_element
