Answer 2

The electronic configuration of an element tells us how electrons are distributed in its atomic orbitals.

Electronic Configuration of Aluminum and its ion

Atomic number of aluminum = 13

Electronic configuration of Al= 1s²2s²2p⁶3s²sp¹

Now, Atomic number of Al³⁺ = 10

Electronic Configuration of Al³⁺ = 1s²2s²2p⁶

Electronic Configuration of Oxygen and its ion

Atomic number of Oxygen = 8

Electronic Configuration of Oxygen (O) = 1s²2s²2p⁴

Atomic number of O²⁻ = 10

Electronic Configuration of O²⁻ =  1s²2s²2p⁶
