The electron construction of chlorine is #1s^2 2s^2 2p^6 3s^2 3p^5# or #"
You are watching: How many valence electrons does chloride have
The #3s^2 3p^5# electrons are 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 below that over there are seven electrons in the outermost circle.
Additionally, a much more basic way of determining the variety of valence electrons would certainly be to just look in ~ what team Cl is in.
It is in team 17, which method it has 7 valence electrons.

Chlorine has actually an atom number 17. Atomic number is the number of protons current in the cell core of an atom. All the atom of an facet have very same atomic number. In every stable atom the number of electrons is same to the variety of protons. Therefore, the variety of electrons is same to the number of protons in an chlorine atom. This means, the the variety of electrons current in an chlorine atom is 17.
The digital configuration the chlorine atom is:-E.C - K together M 2 8 7Where k, l, ,m space the shells/orbits/ power levels of an chlorine atom.
Valence electrons are the number of electrons present in the outermost shell of one atom. Now, the last covering of chlorine atom has 7 electron in it. Therefore, there space 7 valence electrons present in one chlorine atom.
Here, stable means that atom has not created a ion yet.

Chlorine has seven valence electrons.
Chlorine has actually atomic number 17.
The atomic number is the variety of protons existing in the cell nucleus of an atom.All the atom of an element have very same atomic number.
In every stable atom the variety of electrons is same to the variety of protons. Stable means that atom has not developed a ion yet.
Therefore, the number of electrons is same to the number of protons in one chlorine atom.
This means, the the number of electrons present in an chlorine atom is 17.
The energy shells of one atom space in the order K, L, M …
So the electronic configuration of chlorine atom is: K, L, M = 2, 8, 7
Valence electrons room the number of electrons existing in the outermost shell of one atom.
The last shell of a chlorine atom has actually 7 electrons in it.
