Question

If Z = 3, what would be the valency of the element? Also, name the element.

Answer 1

Here is your answer.....

Given,
Z (atomic number)= 3

Electronic configuration=2,1

Valency=Number of electrons in valence sheel =1
So, valency is =1

Name of element is = Lithium.

Answer 2

The valency of the element is 1 and the element is lithium.

* Z stands for atomic number which is 3 here so the electronic configuration should be 2,1. * Therefore the number of electrons in the outermost shell of the electron is 1.

* Hence, the valency of the element is 1 and the element having this configuration is Lithium.
