Explanation:

=>A period is a horizontal row of the periodic table. There are seven periods in the periodic table, with each one beginning at the far left.

A new period begins when a new principal energy level begins filling with electrons.

Period 1 has only two elements (hydrogen and helium), while periods 2 and 3 have 8 elements.
