Question

If z=3 what would be the valency of the element and also name the element?

Answer 1

By Z = 3, we mean that the atomic number of the element is 3. Its electronic configuration is 2, 1. Hence, the valency of the element is 1 (since the outermost shell has only one electron). Therefore, the element with Z = 3 is lithium..

Answer 2

Answer:

Atomic number Z = 3

Electronic configuration = 2(K), T(L)

Valence shell has 1 electron in the outermost shell, so valency of element is 1. The element is Lithium.
