Question

If z = 3 what would be the valency of element . write the name of element ? ​

Answer 1

Answer:

By Z=3, we mean that the Atomic number (Z) of the element is 3.

Its electronic configuration is 2,1.

Hence, the valency of this element is 1 since the outermost shell has only one electron.

Therefore the element with Z=3 is Lithium

Answer 2

Answer:

if z = 3

• the valency of the element would be 1
• the element is lithium (Li)
