Beryllium oxide formed at high temperatures (>800°C) is inert, but dissolves easily in hot aqueous ammonium bifluoride (NH4HF2) or a hot solution of concentrated sulfuric acid (H2SO4) and ammonium sulfate ((NH4)2SO4).

Beryllium is not completely inert, as it can react with acids and water to form beryllium compounds. It is a highly toxic metal, and exposure to beryllium dust or fumes can cause serious health issues such as berylliosis.
Yes. It is the compound of the elements Beryllium and fluorine.
Yes, beryllium has multiple isotopes, with the most common being beryllium-9. Other isotopes of beryllium include beryllium-7 and beryllium-8.
No. Beryllium is a metallic element. However, there is a such thing of beryllium oxide, which forms when beryllium combines with oxygen.
Although beryllium and helium have the same number of valence electrons (two), the underlying reasons for their chemical properties differ. Beryllium is a metal, meaning it readily loses its valence electrons to form positive ions, while helium is an inert gas, meaning its outer electron shell is already filled and it is unlikely to form chemical bonds with other elements. This difference in reactivity leads to distinct chemical behaviors between beryllium and helium.
The word equation for beryllium carbonate is: beryllium carbonate = beryllium oxide + carbon dioxide.
