N the ionic compound aluminum selenide, each atom of aluminum (gains or loses)
Volgvan

Answer:

loses, gains

Explanation:

In the ionic compound aluminum selenide, each atom of aluminum will lose electrons while each atom of selenium will gain the electrons.

An ionic compound is an interatomic bond formed between a metal and non-metal. The metal is less electronegative compared to the non-metal. In this case, the metal will lose electrons to become positively charged whereas the non-metal, selenium will gain the electron to become negatively charged.

The electrostatic attraction between these oppositely charged ions leads to the formation of the ionic bond.

These reactions are the oxidation of methane, carbon monoxide, decomposition of NO and the catalytic combustion of organic compounds.
