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

You are watching: How many valence electrons are in cl

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

In a picture, the valence electrons space the ones in the outermost shell.

You have the right to see in the diagram below that there are 7 electrons in the outermost circle. Additionally, a an ext basic way of determining the number of valence electrons would be to merely look in ~ what team Cl is in.

It is in team 17, which method it has 7 valence electrons.  Shivangi Mangotra

Chlorine has actually an atom number 17. Atomic number is the variety of protons existing in the cell core of one atom. Every the atoms of an aspect have same atomic number. In every stable atom the number of electrons is equal to the number of protons. Therefore, the number of electrons is same to the number of protons in one chlorine atom. This means, that the number of electrons current in an chlorine atom is 17.

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

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

Here, stable means that atom has not created a ion yet.  Ernest Z. · mrpauller.weebly.com

Chlorine has actually seven valence electrons.

Chlorine has atomic number 17.

The atom number is the number of protons current in the cell core of an atom.All the atoms of an element have very same atomic number.

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

Therefore, the number of electrons is same to the number of protons in an chlorine atom.

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

The power shells of an atom are in the order K, L, M …

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

Valence electrons space 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.
