What are the ions of cobalt?

The compounds in which cobalt exhibits the +2 oxidation state (Co2+, the ion being stable in water) are called cobaltous, while those in which cobalt exhibits the +3 oxidation state (Co3+) are called cobaltic. Both Co2+ and Co3+ form numerous coordination compounds, or complexes.

What is the positive ion in potassium selenide?

Two potassium ions, each with a charge of 1+, would give us two positive charges, while one selenide ion, with a charge of 2−, would give us two negative charges. Therefore, the formula is two potassium ions to one selenide ion: K2Se.

What is the correct formula for barium oxide?

Barium oxide has the formula BaO . It’s an ionic compound, so its formula represents the lowest whole number ratio of elements in the compound. So Ba2O2 should be reduced to BaO . The formula for the lead (II) ion is Pb2+ .
