The use of the online site say there are eighteen electrons that are in the chloride ion CI-. The info is useful if you use the chloride in situation.
It have an electron configuration of 2,8,8,SO it contains 8 electrons in it's outer shell.
4V V-Valence Electrons Valence Electrons-Last electron (which is on the outer shell)
The outer shell (N=4) of the copper element has 2 electrons.
Boron has 5 electrons per atom. Boron's electron configuration is 1s2 2s2 2p1. Thus, it has 3 electrons in its outer shell.
Magnesium chloride is an ionic compound. Magnesium has 2 valence electrons, and chlorine has 7. According to the octet rule, each element will bond in such a way that it ends up having 8 electrons in its outer shell--either by adding electrons to its outer shell until it has 8, or by losing all the electrons in its outer shell (that way, the next-largest electron shell--which is already full--becomes the new outer shell). Since magnesium has 2 valence electrons, it will lose two electrons (it's easier to go 2 - 2 = 0 than to go 2 + 6 = 8). Chlorine has 7, so it will gain an electron and have a full (8-electron) outer shell. There must therefore be two chlorines for every magnesium: each chlorine accepts one of the two electrons donated by magnesium. Magnesium forms two ionic bonds: one to each chloride ion.
