text: In these compounds, nitrogen is usually trivalent (though it can be tetravalent in quaternary ammonium salts, R 4 N+), with a lone pair that can confer basicity on the compound by being coordinated to a proton.
text: Nitrogen has five valence electrons and in simple amines it is trivalent, with the two remaining electrons forming a lone pair.
text: It has five electrons in its outer shell and is therefore trivalent in most compounds.
