Cobalt (II) Oxide is the systematic name for the formula CoO.
The chemical formula that gives total number of atoms of each element in one molecule of a compound is called Molecular Formula.
Oxidation state is also known as oxidation number. It is defined as the atom is equal to the total number of electrons which have been removed from the element in order to form chemical bond with other atom.
Now find the oxidation state of Co in CoO.
Assume the oxidation state of Co in CoO be x
x + 1 × (-2) = 0
x -2 = 0
x = +2
Oxidation state of Co is +2 or (II)
Thus from the above conclusion we can say that The systematic name for the formula CoO is Cobalt (II) Oxide.
