Question

Atomic number of an element is 26 . Write down its subshell electronic configuration .

Answer 1

Answer:

The subshell electronic configuration is $1s^{2} 2s^{2} 2p^{6} 3s^{2}3p^{6} 4s^{2} 3d^{6}$

Explanation:

A subdivision of electron shells separated by electron orbitals is called a subshell. In an electron configuration, subshells are labeled s, p, d, and f.

Given the atomic number of an element is 26.

we know that iron(Fe) has an atomic number of 26.

That is the total number of electrons is 26.

Therefore the subshell electronic configuration $1s^{2} 2s^{2} 2p^{6} 3s^{2}3p^{6} 4s^{2} 3d^{6}$
