The tantalum nitride films consist of a mixture of metallic tantalum, Î²-TaN 0.05, Î³-Ta 2 N and cubic/hexagonal TaN phases, their composition depending on both the ion dose and ion energy. 13. The kinetics of nitridation is characterised by two stages.
1 Both oxygen atoms currently have 8 electrons assigned to them. 2  The nitrogen atom has only 6 electrons assigned to it. 3  One of the lone pairs on an oxygen atom must form a double bond, but either atom will work equally well. 4  Therefore, there is a resonance structure.he formula of the nitrite ion is. 1  Nitrogen is the less electronegative atom of the two, so it is the central atom by multiple criteria. 2  Count valence electrons. 3  Nitrogen has 5 valence electrons; each oxygen has 6, for a total of (6 Ã 2) + 5 = 17.
