Question

The metallic oxide which do not form alkali

Answer 1

Answer:

They do form oxides by direct combination with oxygen. Quoting directly from Wikipedia: “Sodium at standard temperature and pressure is a soft silvery metal that combines with oxygen in air and forms grayish white sodium oxide unless immersed in oil or inert gas, which are the conditions it is usually stored in.” However, sodium readily reacts with water to produce NaOH and H2 gas so in a humid environment it will react with water vapor to produce NaOH on the surface. But NaOH reacts with Na to produce Na2O, so either way you end up with Na2O.
