Cobalt nitrate is an ionic compound.
Covalent
Ionic - electron transfer Covalent - electron share (co - share)
Cobalt is an element. Polar, non-polar and ionic are terms to describe compounds. They measure whether the compound as delta charges or their form of bonding. Thus, it is not applicable to cobalt (Co), which is an element and pure by itself.
I'm not sure what you mean by "purely covalent", since the ionic-vs-covalent distinction is expressed in terms of electronegativity, which can take a range of values (higher values = more ionic). CO is very much a covalent compound though.
CoBr2 is ionically bonded. This is because there is a metal (Co-cobalt) and a non metal (Br-bromine).
No, it is covalent.
Covalent
Carbon monoxide.

Since carbon monoxide is not an ionic compound it technically doesn't have an ionic formula. The molecular formula for carbon monoxide is CO
A binary compound contains two elements. An ionic compound will contain cations and anions and form an infinite lattice for example sodium chloride, NaCl, calcium fluoride, CaF2. A binary molecular compound will form molecules for example water, H2O, carbon monoxide, CO. The ionic compounds will generally be high melting brittle solids, molecular compounds will vary from gases, (lighter ones) through to liquids and solids, for example the alkanesCnH2n+2,Ionic compounds are generally formed by metals and non-metals, molecular generally from non-metals.
Covalent bonds are formed between a metal and a non-metal. Co is cobalt, a metal, so it will react with O to form CuO, a compound with ionic bonds.
CO is molecular
