Question

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

Answer 1

Answer:

lithium

If z = 3, i.e., atomic number is 3. Its electronic configuration is 2, 1. Hence, the valency of the element is 1 (since the outermost shell has only one electron). Then element is lithium.

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

${ \underline{ \boxed{ \large{ \bf{ \gray{Answer}}}}}}$

Z = 3

Atomic no. of element = 3

Its electronic configuration

= ＫＬ

2,1

Its Valency = 1(No. of electrons in the valence shell.)

Name of the element with atomic number 3 and valency 1 is Lithium.
