The electron construction of chlorine is #1s^2 2s^2 2p^6 3s^2 3p^5# or #"
You are watching: How many core electrons are in a chlorine atom
The #3s^2 3p^5# electrons room the outermost electrons, so chlorine has actually seven valence electrons.
In a picture, the valence electrons are the persons in the outermost shell.
You deserve to see in the diagram below that over there are seven electrons in the outermost circle.
Additionally, a more basic means of determining the variety of valence electrons would be to simply look in ~ what team 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 existing in the cell nucleus of an atom. Every the atom of an aspect have same atomic number. In every stable atom the variety of electrons is equal to the variety of protons. Therefore, the number of electrons is same to the number of protons in one chlorine atom. This means, the the variety of electrons current in one chlorine atom is 17.
The digital configuration that chlorine atom is:-E.C - K l M 2 8 7Where k, l, ,m are the shells/orbits/ power levels of one chlorine atom.
Valence electrons space the variety of electrons current in the outermost shell of an atom. Now, the last covering of chlorine atom has actually 7 electrons in it. Therefore, there are 7 valence electrons current in one chlorine atom.
Here, stable way that atom has actually not formed a ion yet.

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