copper II compounds are more stable because it is hard
The Center
Type I Compounds are formed with metals that have only one valence, (one type of oxidation state). Type II Compounds are with metals that can form more than one type of oxidation state. A few off the top of my head are: Cr, Mn, Fe, Co, Cu, Au, Hg, Sn, Pb.
ABSOLUTELY!! In fact, this is called Type II Superconductors. Many physicists around the world are producing compounds hoping to achieve superconducitivty at higher temperatures or even room temperatures.
Every type of atom can form compounds.
Well depends what you mean by how many different types of compounds. In total? Or type 1 , and 2 etc. there is Type 1-Binary Compounds Type 2- Binary Trans-metallic Compounds Type 3- Binary Molecular Compounds Type 4- Ternary Compounds etc. these contains vast amounts of compounds so gives you an idea.

Boron or copper(II) compounds (excluding halogenides).
This compound is cobalt(II) chloride.
Type II
These are the covalent compounds.
