Why do the chemical properties cycle through each period? every eighth element starting with hydrogen restarts the transition from metal to inert gas. elements with atomic numbers which are multiples of eight start a new period. the outermost shell of all atoms with two or more electron shells will not have more than 8 electrons. each period represents a cycle of completing the outer electron shell.
