If you had a piece of metal, you could use these properties to determine which element it is. Iron has different physical and chemical properties than the other two elements. The density of iron is much less than cobalt or nickel, and it reacts with oxygen in the air.
Their densities are very similar as is their reactivity to air. You need some other method.
It is soft in nature . Because of its dramatic color change and the ease of the hydration/dehydration reaction, "cobalt chloride" is used as an indicator for water in desiccants. Its formula is CoCl2.6H2O
There are no compounds in Cobalt. It is completely impossible, because Cobalt is an element, and compounds are made up of elements. If this is what you meant to ask, then there a a lot of compounds with Cobalt in them. One example is Cobalt (III) Fluoride, chemical formula CoF3. Any compound with a "Co" (the "C" must be capitalized and the "o" must lowercase) in it contains Cobalt.
Cobalt! duhh
no, cobalt is a metal.
The chemical name is Cobalt(II) Fluoride Hexahydrate.
zinc is more reactive and is higher in the reactivity series.
20.3g Al

Yes, cobalt form many chemical compounds as cobalt nitrate, cobalt chloride, cobalt sulfate, cobalt sulfide, etc.

cobalt = Cobalt/Kobalt
Cobalt (I) chloride = Cobalt monochloride = CoCl Cobalt (II) chloride = Cobalt dichloride = CoCl2 Cobalt (III) chloride = Cobalt trichloride = CoCl3
The given are two isotopes of cobalt, hence have different numbers of neutrons. As there are same number of electrons (as well as protons) the chemical properties such as ionisation, bonding etc. do not differ. But due to the different amounts of masses, they show differed physical properties including density, boiling point etc.
Tungsten carbides are generally called as carbides. Cobalt with Tungsten carbide acts as a binder. When Cobalt added with other elements like Ni / Cr / Mo / Ti are called as cemented carbides. Sintering is a thermal treatment given to these carbides so as to eleminate the porosities and densify them. During this treatment cobalt binds the WC particles and we get high density.
Cobalt is generally bivalent or trivalent. So either Cobalt (II) or Cobalt (III).
