Explanation:

The elements of a group have similar chemical properties but in a period they have different chemical properties. This is because the chemicals properties depend on no of valence electrons. As in a group all elements have same no of valence electron that's why they have similar chemical properties but in a period the no of valence electron varies that's why they differ in chemical properties.

because in the same period every element has different valance electron due to which they have different chemical and physical properties. the valence electron even decides if a element is a metal or a non-metal or a metalloid.
