Explanation:
2.Nitrogen has a total of 5 valence electrons, so doubling that, we would have a total of 10 valence electrons with two nitrogen atoms. The octet requires an atom to have 8 total electrons in order to have a full valence shell, therefore it needs to have a triple bond.
3.The total number of valence electrons in magnesium chloride is sixteen. The symbols of magnesium and chlorine are written as, A covalent bond representing two electrons is placed as a line between chlorine and magnesium atoms.
4.Neon, with its configuration ending in s2p6, has eight valence electrons.
5.one valence electron
In the case of gold, there is only one valence electron in its valence level.
