Asked by admin @ 20/08/2021 in Science viewed by 331 People

An element A forms two oxides AO and AO2. The oxide AO is neutral whereas the oxide AO2 is acidic in nature. Would you call element A, a metal or a non-metal?

Answered by admin @ 20/08/2021

Element A is nonmetal .
For example :
carbon is nonmetal which forms two oxides CO and CO2.
CO is neutral and CO2 is acidic in nature.
