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.)
characteristics of salts & oxides
No neutral element has these characteristics. However, the oxide ion, O-2, does have them.
Selenium is a terminal oxide and it exists in a number of allotropic forms.
Examples of compounds are iron oxide, hydrochloric acid, water, carbon dioxide, ammonia, salt.
Lloyd W. Root has written: 'Phonon attenuation characteristics of manganous oxide (MnO)'
These characteristics were: density, melting point, atomic mass, type of oxide and chloride.
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.
Copper (I) Oxide or Cuprous Oxide
Magnesium Oxide
oxide is not. But nitrous oxide is!
Sodium oxide, Magnesium oxide, Copper oxide, Acidic oxide, Amphoteric oxide
Yes it is an amphoteric oxide as it has both basic oxide and acidic oxide properties.
