Question

What is the correct general outer electronic configuration of group 13 elements?

Answer 1

Electronic configuration of Group $13$

• The general outer electronic configuration of these elements is $n{s}^{2}n{p}^1$ .
• These elements have completely filled s orbitals.

Elements of group $13$

• The elements present in group $13$ are Boron$\left(\mathrm{B}\right)$, Aluminum$\left[\mathrm{Al}\right]$, Gallium$\left(\mathrm{Ga}\right)$, Indium$\left(\mathrm{In}\right)$, and Thallium$\left[\mathrm{Tl}\right]$.

Example

• The atomic number of boron is $5$.
• The electronic configuration of boron is $1s^{2}2s^{2}2p^1$.
