None of the above, gold is an element.
The oxide formed in gold is neither an acid nor a base. Gold oxide (Au2O3) is considered to be amphoteric, which means it can exhibit characteristics of both an acid and a base depending on the reaction it undergoes. It can react with both acids and bases to form different compounds.
Gold does not react directly with oxygen, however if you succeed in getting gold oxide indirectly, it decomposes at 205C. The oxide is neither acid nor base however gold ions are acidic (like protons are acidic)
Gold oxide is neither an acid nor a base. It is a metal oxide, which means it is a compound that contains a metal (gold) and oxygen. Metal oxides tend to be basic in nature, meaning they can react with acids to form salts and water.
Acid
acid.
Aluminum oxide is classified as a metal oxide. Specifically, it is known as an amphoteric oxide, meaning it can react both as an acid (when combined with a base) and as a base (when combined with an acid).
When a metal oxide neutralizes an acid, it produces a salt and water. This reaction is a type of acid-base reaction where the metal oxide acts as a base and the acid acts as an acid. The salt formed usually contains the metal cation from the metal oxide and the anion from the acid.
The oxide of fermium is not known.
Oxygen oxide is not a real substance.
No. Copper oxide has no acid-base properties.
Gold is neither an acid nor a base, according to most definitions of acidity.
Copper oxide is a base, since it neutralises dilute acid.
