They are usually dull and brittle, form crystals and are insoluble (apart from potassium, sodium, lithium and ammonium oxides).
Metal oxides are largely basic.
Non-metal oxides are acidic.
Aluminium and Zinc oxides are amphoteric (can act as a base or and acid by being able to both donate and accept protons.)
No neutral element has these characteristics. However, the oxide ion, O-2, does have them.

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.
HIT OXIDE, or High-Temperature Oxide, typically refers to a class of materials that exhibit specific properties at elevated temperatures, often used in applications like catalysis, electronics, or materials science. These oxides can include compounds such as titanium dioxide or cerium oxide, known for their stability and performance under thermal stress. Their unique characteristics make them valuable in various industrial processes, including energy production and environmental remediation.
Copper (I) Oxide or Cuprous Oxide
Vanadium oxides can have both covalent and ionic characteristics depending on the oxidation state of vanadium and the oxygen coordination. For example, vanadium(V) oxide (V2O5) tends to have more covalent character due to the presence of multiple vanadium-oxygen bonds.
Yes it is an amphoteric oxide as it has both basic oxide and acidic oxide properties.
Magnesium Oxide
Beryllium oxide (BeO) is amphoteric, meaning it can act as both an acid and a base depending on the reaction it is involved in. In general, BeO tends to exhibit more basic characteristics in reactions, but it can also exhibit acidic properties in certain situations.
Copper(I) Oxide: Cu2O (cuprous oxide)orCopper(II) Oxide: CuO (cupric oxide)it can be both.
