Chlorine has 7 electrons in its outer shell. It needs one more electron to achieve a full outer shell of 8 electrons, making it highly reactive.
Chlorine typically has 17 electrons. In its ground state, chlorine has 7 valence electrons in its outer shell. When it gains one electron, it becomes Cl-, making its total number of electrons 18.
I think that because chlorine has 17 electrons in all, and ten of them are filled up on the first two shells, then seven of them should be on the third shell, so seven of them are valance electrons.
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.
Iodine has 7 valence electrons.
7
Fluorine has 7 valence electrons, while chlorine has 7 valence electrons.
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 has 7 electrons in its outer shell. It needs one more electron to achieve a full outer shell of 8 electrons, making it highly reactive.
The 3p subshell of chlorine has valence electrons. Chlorine has 7 valence electrons in the 3p subshell.
Chlorine typically has 17 electrons. In its ground state, chlorine has 7 valence electrons in its outer shell. When it gains one electron, it becomes Cl-, making its total number of electrons 18.
Chlorine is an electron acceptor. It has a strong tendency to gain one electron to achieve a stable electron configuration.
2 valance electrons
There are 27 valance electrons.
The groups, or families of elements have the same number of valance electrons and this information can be found at the top of the periodic table. For instance; 1A represents the alkali metals and they all have a valance number of 1. Then go from the left to the right and look at the top of the table. 8A represents the farthest left family of elements, from top to bottom, the Nobel gasses. They have a full valance shell of 8 electrons.
I think that because chlorine has 17 electrons in all, and ten of them are filled up on the first two shells, then seven of them should be on the third shell, so seven of them are valance electrons.
