Question

What is the noble gas notation for chlorine

Answer 1

Answer : The electronic configuration of chlorine (Cl) in noble gas notation will be:

$[Ne]3s^23p^5$

Explanation :

Electronic configuration : It is defined as the representation of electrons around the nucleus of an atom.

Number of electrons in an atom are determined by the electronic configuration.

Noble-Gas notation : It is defined as the representation of electron configuration of an element by using the noble gas directly before the element on the periodic table.

Chlorine is the non-metal that belongs to group 17 and has 17 electrons in their shell.

The electronic configuration of chlorine (Cl) will be:

$1s^22s^22p^63s^23p^5$

The electronic configuration of neon (Ne) will be:

$1s^22s^22p^6$

So, the electronic configuration of chlorine (Cl) in noble gas notation will be:

$[Ne]3s^23p^5$

Answer 2

The noble gas notation for chlorine is [Ne]3s^2 3p^5
