The electron construction of chlorine is #1s^2 2s^2 2p^6 3s^2 3p^5# or #""3s^2 3p^5#.

You are watching: Click on the correct electron configuration for chlorine

The #3s^2 3p^5# electrons are the outermost electrons, for this reason chlorine has actually seven valence electrons.

In a picture, the valence electrons are the people in the outermost shell.

You have the right to see in the diagram below that there are seven electrons in the outermost circle.

*

Additionally, a an ext basic method of identify the variety of valence electrons would be to just look at what group Cl is in.

It is in group 17, which way it has actually 7 valence electrons.

Chlorine has actually an atom number 17. Atomic number is the variety of protons present in the cell nucleus of an atom. All the atoms of an element have very same atomic number. In every stable atom the number of electrons is equal to the number of protons. Therefore, the variety of electrons is equal to the variety of protons in an chlorine atom. This means, that the variety of electrons existing in one chlorine atom is 17.

The electronic configuration that chlorine atom is:-E.C - K together M 2 8 7Where k, l, ,m room the shells/orbits/ power levels of an chlorine atom.

Valence electrons are the number of electrons existing in the outermost shell of an atom. Now, the last covering of chlorine atom has 7 electron in it. Therefore, there space 7 valence electrons current in an chlorine atom.

Here, stable means that atom has actually not formed a ion yet.

Chlorine has actually seven valence electrons.

Chlorine has actually atomic number 17.

The atom number is the variety of protons current in the nucleus of one atom.All the atoms of an aspect have very same atomic number.

In every stable atom the number of electrons is same to the variety of protons. Stable means that atom has not developed a ion yet.

Therefore, the variety of electrons is same to the variety of protons in one chlorine atom.

This means, the the number of electrons present in an chlorine atom is 17.

The power shells of an atom room in the stimulate K, L, M …

So the electronic configuration of chlorine atom is: K, L, M = 2, 8, 7

Valence electrons room the variety of electrons existing in the outermost covering of an atom.

The last covering of a chlorine atom has actually 7 electron in it.
