The number of electrons is 18.
A chlorine anion has gained one electron, resulting in a total of 18 electrons. A neutral chlorine atom has 17 electrons, but gaining one electron makes it negatively charged, with a total of 18 electrons in the anion.
An oxygen anion with a charge of -2 has 10 electrons. Oxygen normally has 8 electrons, but an anion with a -2 charge gains two additional electrons.
A Cl⁻ anion has gained one electron compared to a neutral chlorine atom. A neutral chlorine atom has 7 valence electrons, with the electron configuration of [Ne] 3s² 3p⁵. Therefore, in the Cl⁻ anion, there are 6 electrons in the 3p subshell, as it now has a total of 8 valence electrons (3s² 3p⁶).
The anion of OCl (hypochlorite ion) has 8 valence electrons. This is because oxygen contributes 6 valence electrons and chlorine contributes 7 valence electrons. The overall negative charge of the anion adds one more electron, totaling 8 valence electrons.
A single chlorine atom has 17p+ (Protons) and 17e- (Electrons). Chlorine will form a 171- anion by gaining one electron, completing the valence shell as an octet.
Chloride anion has 8 valence electrons.
Cl- has 8 valence electrons. This is because chlorine, in its neutral state, has 7 valence electrons (group 17), and the -1 charge of the chloride ion indicates the addition of an extra electron.
Chlorine with 17 protons and a -1 charge has 18 electrons. This is because the number of electrons should equal the number of protons (in this case, 17) plus or minus the charge (in this case, -1).
how many electrons does chlorine have
An oxygen anion has 10 electrons, because it gains two electrons to achieve a full valence shell of 8 electrons.
17 protons and 17 electrons in chlorine.
Chlorine has 7 valence electrons.
