Question

is aluminate a trivalent electronegative​

Answer 1

Answer:

In chemistry, aluminium(I) refers to monovalent aluminium (+1 oxidation state) in both ionic and covalent bonds. Along with aluminium(II), it is an extremely unstable form of aluminium.

A trivalent electropositive ion means having the valency of plus three. Aluminium atom loses three electrons from its outermost (valence) shell to form trivalent positive ion. ... Nitride (N^-3) ions can attract three electrons to its outermost shell to form trivalent negative ion.
