Cl− is formed from adding one electron so the new electronic configuration is 2, 8, 8. So the valence electrons is 8.

The chlorine atom has seven valence electrons. The shell of the chlorine ion ($C{l^ - }$) has 18 electrons. There are eight valence electrons in all.

Therefore, the total number of valence electrons in chlorine ion is Eight. Hence option (B) is correct.

1 сент. 2017 г. · Chlorine has total 17 electrons in its atom. Out which 10 are inner or core electrons and 7 are valence electrons located in the 3s and 3p shells.

9 янв. 2020 г. · The number of electrons is equal to the number of protons in an chlorine atom. This means, that the number of electrons present in an chlorine atom is 17.

Chlorine is in group 17, the halogens, which all have 7 valence electrons. Because halogens only require one more electron to fill their valence shell.
