Rubidium and oxygen
Did you know?
Rubidium oxide is the chemical compound with the formula Rb2O. Rubidium oxide is highly reactive towards water, and therefore it would not be expected to occur naturally. The rubidium content in minerals is often calculated and quoted in terms of Rb2O. In reality, the rubidium is typically present as a component of (actually, an impurity in) silicate or aluminosilicate. A major source of rubidium is Webb28 nov. 2024 · When aluminum and oxygen become an ionic compound the formula is?, Answer. Since two aluminum ions each with +3 charge will balance the charge on three oxide ions with -2 charge, the formula will be Al2O3. The name is aluminum oxide because it is made from aluminum ions and oxide ions.
