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

You are watching: An atom of chlorine has several valence electrons in its

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

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

You deserve to see in the diagram below that over there are seven electrons in the outermost circle.

*

Additionally, a an ext basic method of identify the number of valence electrons would be to simply look at what team Cl is in.

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

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

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

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

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

Chlorine has seven valence electrons.

Chlorine has actually atomic number 17.

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

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

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

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

The energy shells of an atom space in the order K, L, M …

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

Valence electrons space the number of electrons existing in the outermost covering of one atom.

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

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

Here is a video which gives a quick conversation of exactly how to recognize how many valence electrons atom of different aspects have.Video from: Noel Pauller
