Most metals form which type of oxide?
ABasic oxide
BAcidic oxide only

Answer & Solution
Correct answer: A. Basic oxide
1. The chapter section 7A on metals vs non-metals lists oxide behaviour.
2. Metals like Na, K, Ca form oxides that dissolve to give bases.
3. Non-metals form acidic or neutral oxides.
4. So most metal oxides are basic.
