Question

Electron configuration for Ar

Answer 1

Answer : The electronic configuration of argon (Ar) is, $1s^22s^22p^63s^23p^6$

Explanation :

Element is, Argon (Ar)

Atomic number of argon = 18

The number of electrons = 18

As we know that the number of electrons is equal to the number of protons and the number of proton is equal to the atomic number.

Electronic configuration : It is defined as the arrangement or distribution of electron of atom in a atomic orbital.

Hence, the electronic configuration of argon is,

$1s^22s^22p^63s^23p^6$
