a. Mg

b.Ca2+

c. Ar

d. Mg2+

Short Answer

Expert verified

a. 1s22s22p63s2

b.1s22s22p63s2 3p6

c.1s22s22p63s2 3p6

d.1s22s22p6

Step by step solution

01

Write down the electronic configuration

a. 1s22s22p63s2

b.1s22s22p63s2 3p6

c.1s22s22p63s2 3p6

d.1s22s22p6

02

write down the ground state electronic configuration.

Follow the Hunds rule to fill up the orbitals.

Hunds rule states that every orbital in a subshell is first occupied singly having the same spin before it is doubly occupied.
