Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The formation of magnesium nitride(Mg3N2) involves the transfer of electrons from three magnesium atoms to two nitrogen atoms. How many electrons are received by each of the nitrogen atoms?

A	1
B	2
C	3
D	4

Explanation:

Detailed explanation-1: -Answer and Explanation: Magnesium (Mg) loses 6 electrons and nitrogen (N) gains 6 electrons to form Mg3 N2 (magnesium nitride). Atoms do not form compounds.

Detailed explanation-2: -Mg has 2 valence electrons and loses these 2 valence electrons to form Mg2+ ion. N has 5 valence electrons. It gains 3 valence electrons to form N3− ion.

Detailed explanation-3: -The whole number of valence electrons existing in Mg3N2 is the sum of valence electrons present in 3 Mg atoms and valence electrons present in 2 N atoms. So the whole number of valence electrons existing in Mg3N2 is 16.

Detailed explanation-4: -The chemical formula for this reaction is Mg+N2→MgN2.

Detailed explanation-5: -It is an inorganic compound of magnesium and nitrogen consisting of 3 atoms of Magnesium and two atoms of nitrogen. The chemical or molecular formula of Magnesium Nitride Formula is Mg3N2.
