Question

Elements of same group have same no.of valency electron

Answer 1

Answer:

s it is correct according to the properties of periodic table pls mark it as the brainliest and follow me

Answer 2

Answer:

The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.

The valency of an elements is determined by the number of valence electrons present in the outer shell of an atom. Since all the elements of a group have the same number of valence electrons. Therefore, they have same valency.

For example, alkali metals have one valence electron. Hence, their valence is 1. Similarly, alkaline earth metals have two valence electrons.
