is dull non metal?
Answered by GPT 3.5
No, dullness or luster does not solely determine if a substance is a metal or not. However, metals tend to have a shiny or metallic luster, while non-metals generally have a dull or non-metallic appearance. So, if a substance is dull, it could be an indicator that it is a non-metal, but it is not a definitive characteristic.
