    does CoO exist?

    I don’t know it is just written like this in my inorganic book

    If I may know, is this A level or GCSE?

    by more covalent, do you mean which has more bonds? If so, then Co2O3, In2S3, CrCl3 are more covalent because it has more bonds compared to the one each one is being compared with

    Hope this helps.

    This is a weird question though

    A bond being more covalent doesn't mean it has more bonds...

    There is greater tendency towards covalency as the oxidation state gets larger. This is because the higher charge density of the positive ion distorts the ionic charge cloud.

    Hence Co2O3 is (slightly) more covalent than CoO.

    Apply the same rules to the others.

    Oh my bad! i forgot Co was cobalt.. I read it as carbon monoxide Oxide instead of cobalt(II)oxide

    Also Carbon Monoxide Oxide would be... CO2. You may have heard of it
