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 in cl

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

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

You have the right to see in the diagram listed below that there are 7 electrons in the outermost circle.

Additionally, a much more basic way of determining the variety of valence electrons would be to simply look in ~ what group Cl is in.

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

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

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

Valence electrons are the variety of electrons existing in the outermost shell of one atom. Now, the last covering of chlorine atom has actually 7 electrons in it. Therefore, there room 7 valence electrons present in an chlorine atom.

Here, stable method that atom has not developed a ion yet.

Chlorine has actually seven valence electrons.

Chlorine has atomic number 17.

The atomic number is the variety of protons present in the cell nucleus of an atom.All the atom of an element have exact same atomic number.

In every stable atom the number of electrons is same to the number of protons. Stable method that atom has actually not formed 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 current in an chlorine atom is 17.

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

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

Valence electrons room the number of electrons present in the outermost covering of one atom.

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

Therefore, there space 7 valence electrons in an chlorine atom.
