There are 12 electrons in the electron shell of magnesium, the same number as protons. As for the outermost shell, it would be 3s2, meaning there are two electrons in the third "s" shell.
The element chlorine has seven electrons in its valence shell.
chlorine has 6 electrons in the outer shell. although these have a special name, they are called valance electrons.
Cl is in the 17 group. It is in the 3rd period. It has 3 energy levels.
The electronic configuration of chlorine is 2,8,7 So there are 7 electrons in the valence shell (or highest energy level).
Chlorine has 7 electrons in its outer shell. It needs one more electron to achieve a full outer shell of 8 electrons, which is why chlorine typically gains an electron to form Cl- ion in chemical reactions.

two
Chlorine has 17 electrons, distributed in the following way: 2 in first shell 8 in second shell 7 in third (outer) shell Therefore Chlorine has 7 electrons in its outer shell.
Fluorine has 7 electrons in its outer shell, while chlorine has 7 electrons in its outer shell as well. Both elements belong to Group 17 of the periodic table, also known as the halogens, which have 7 valence electrons.
