chlorine has 6 electrons in the outer shell. although these have a special name, they are called valance electrons.
it has 6 valance electrons, the number of electrons can be determined by the number of protons it has, which is the same as it's atomic number.
Chlorine
Chlorine is number 17 in the periodic table, so using the electron shell arrangement,2:8:7:It has 7 electrons in its valance shell so its charge becomes Cl7+ when these 7 electrons are 'donated' (= lost to, as reductant) to oxygen (only in oxyacid or salt perchlorate).Other valence values are +5, +3 and +1 in oxyacids: chlorate, chlorite and hypochlorite, respectively.

chlorine has 6 electrons in the outer shell. although these have a special name, they are called valance electrons.
Chlorine has 7 valance electrons so the easiest way for it to fill it's valance shell and have an octet is to be an electron acceptor; an anion.
Since fluorine and chlorine are in family 7A, they each have 7 valence electrons. The number of the family corresponds to the number of valence electrons.
it has 6 valance electrons, the number of electrons can be determined by the number of protons it has, which is the same as it's atomic number.
Chlorine
Nitrogen has 7 electrons, oxygen has 8 electrons, and chlorine has 9 electrons. That is the total electron count, for inner and outer shells. If you are only concerned with the valance electrons, then it is 5 for nitrogen, 6 for oxygen, and 7 for chlorine.
Chlorine is number 17 in the periodic table, so using the electron shell arrangement,2:8:7:It has 7 electrons in its valance shell so its charge becomes Cl7+ when these 7 electrons are 'donated' (= lost to, as reductant) to oxygen (only in oxyacid or salt perchlorate).Other valence values are +5, +3 and +1 in oxyacids: chlorate, chlorite and hypochlorite, respectively.
By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons
2 valance electrons
There are 27 valance electrons.
