Final answer:
The correct name for the compound made from beryllium and oxygen is Beryllium oxide, with the chemical formula BeO.
Step-by-step explanation:
The compound made from beryllium and oxygen is correctly named Beryllium oxide. This is because beryllium typically forms a +2 oxidation state and, when combined with oxygen, which has a -2 oxidation state, forms a neutral compound. Since there is one oxygen atom for every beryllium atom, the correct formula is BeO, and we do not need to specify the number of oxygen atoms as we would with prefixes like 'di-' or 'mono-' when there is more than one type of atom present.
