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.
The reaction of aluminum with copper II sulfate solution is a redox reaction. Aluminum displaces copper from the copper II ion in the copper sulfate solution, forming aluminum sulfate and copper metal.
Some metal oxides that decompose when heated include lead(II) oxide (PbO), mercury(I) oxide (Hg2O), and copper(II) oxide (CuO). When heated, these metal oxides break down into their respective metal and oxygen gas.
PbI2, lead(II) iodide, is an ionic compound. Lead(II) is a metal and iodide is a non-metal, so they typically form ionic bonds.
Cinnabar is mercury(II) sulphide and the metal is mercury.
The chemical name for Fe(NO3)2 is iron(II) nitrate.
Strontium iodide (SrI2) is classified as a type II ionic compound. In type II compounds, the metal can form more than one type of ion, and in the case of SrI2, strontium typically forms a +2 oxidation state. This characteristic distinguishes it from type I compounds, where the metal has a fixed oxidation state.
Type II implies a compound of a transition metal such as iron which can have one of a number of oxidation states. Ternary implies a containing three different elements such as sodium carbonate. There are two type II ternary iron sulphates, iron (II) sulphate and iron (III) sulphate. Please see the link.
Type II compounds typically involve metal atoms that can form ionic bonds with nonmetals. Metals that do not commonly participate in these types of compounds include noble metals like gold (Au) and platinum (Pt), as they tend to be resistant to oxidation and do not easily form ions. Therefore, either of these metals would not be involved in the formation of a type II compound.

A polyvalent metal is a metal that can have different charges. the four polyvalent metals are: copper which can be +1 or +1 (I, II) iron which can be +2 or +3 (II, III) lead which can be +2 or +4 (II, IV) tin which can be +2 or +4 (II, IV

Ionic bond. The metal (iron) gives up electrons to the non-metal (bromine.)
iron (II)
Either Type I, Type II or Type III will be fine.........
No a type II card is twice as thick as a type I slot (but a type I card WILL fit in a type II slot)
