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.

The correct answer would be the third option. The chemical properties cycle through each period because the atoms' outermost shells having two or more electron shells cannot have more than eight electrons. This is following the octet rule.
