(A) 12(B) 6(C) 3(D) 2 jjreader06 jjreader06 01/07/2019 A. Magnesium has 12 electrons, now remove 2 and you get 10 electrons. How many valence electrons does Aluminum Have? Q. So, the number of electrons is also 12 for Magnesium. The remaining "ions" also have twice the charge and so there will be more attraction between "ions" and "sea". Magnesium, in its elemental form, has 12 protons and 12 electrons. You can also judge the number of valence electrons in an element by referring to the group it belongs to. please try to answer mine. How many valence electrons does magnesium have? 30 seconds . Both of these electrons become delocalised, so the "sea" has twice the electron density as it does in sodium. Mg 3 N 2(s) + 6 H 2 O (l) → 3 Mg(OH) 2(aq) + 2 NH 3(g) In fact, when magnesium is burned in air, some magnesium nitride is formed in addition to the principal product, magnesium oxide . 6. Symbol: Mg. Atomic Number: 12. 2. +2. The final formula of magnesium nitride is Mg 3 N 2. Answers: 2 Get Other questions on the subject: Chemistry. What is the electron configuration of the oxide ion (O^2-) 1s^2 2s^2 2p^6. How many valence electrons does oxygen have? Ionic compounds are formed as the result of the formation of positive and negative ions. Magnesium nitride reacts with water to produce magnesium hydroxide and ammonia gas, as do many metal nitrides. Noble gases (Group 18) = Ne, Ar, Kr, etc = 8 valence electrons (exception: He = only has 2 valence electrons) The transition metals (Groups 3 - 12) all have one or two valence electrons, although they can treat d-shell electrons as valence electrons and effectively have anywhere from 1 to 8 valence electrons.
