31. Antimony is like a nonmetal in that it is a brittle, crystalline solid, has poor electrical and heat conductivity, and has a low boiling point. However, it is also like a metal because of its shiny silver appearance and ability to form alloys. Into which group should antimony be placed? 32.
Best Answer: a) As it contains a metal (Ca) and non metals (N and O), it is an ionic compound. b) Hydrogen Selenide contains two non metals, so it is a covalent compound.mmonium is a polyatomic cation and contains only nonmetals. So it is possible to have nonmetals that are found in ammonium, nitrogen and hydrogen, in the form of NH4 with a positive charge, combined with anions that are negatively charged and have an ionic compound and still have no metals atoms contained in it.
