Question

Identify and name the metals out of the following element whose electronic configurations are given below: $2,8,2$

Answer 1

Electronic Configuration: The electronic configuration of an element is a symbolic notation of the manner in which the electrons of its atoms are distributed over different atomic orbitals.

• The electronic configuration: $2,8,2$
• So, the atomic number of element = 2 + 8 + 2 =12
• Hence, the element is Magnesium.
• The electronic configuration is represented by: Magnesium (Z=$12$)= $1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^2$

Therefore, the name of the metal is Magnesium ($\mathrm{Mg}$).
