$T e$

Step 1

The electron configuration is the arrangement of electrons of an atom. It concerns the way electrons are distributed in the orbitals of the atom. There are $4$ orbital types ( $s$ , $p$ , $d$ , $f$ ) and up to $7$ different energy levels where an electron may reside.

$1 s^{2} \cdot 2 s^{2} \cdot 2 p^{6} \cdot 3 s^{2} \cdot 3 p^{6} \cdot 4 s^{2} \cdot 4 d^{10} \cdot 5 s^{2} \cdot 5 p^{4}$
