WebJun 9, 2014 · [2,8]^(2+) A magnesium atom has atomic number 12, so 12 protons in the nucleus and therefore 12 electrons. These are arranged 2 in the innermost (n=1) shell, then 8 in the next (n=2) shell, and the last two in the n=3 shell. Therefore a magnesium atom is [2,8,2] The magnesium ion Mg^(2+) is formed when the magnesium atom loses the two … Web(a) magnesium (Mg) (b) aluminum (Al) (c) bromine (Br) For example, oxygen forms ionic compounds as an anion with -2 charge because it needs to gain two electrons to have the same electron configuration as neon. Gallium, on the other hand, has a +3 charge because it needs to lose three electrons to have the same electron configuration as argon.

WebWhen forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. We can use this method to predict the charges of ions in ionic compounds.
