Question

if z=13 write the name of element ,symbol,atomic mass, valancey,number of electrons, protons ,and ,neutrons, electric confurigation and also draw electron distribution in shells class 9​

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.
