Give reasons why the lowest oxide of transition metal is basic, the highest is amphoteric/acidic
Options
- AThe lowest oxide contains metal ions in their highest oxidation states, promoting basicity.
- BIn the lowest oxide,some valence electrons of the metal atom not involved in bonding can be donated i.e.act as
- CThe lowest oxide has metal ions with a strong tendency to accept electrons, leading to basicity.
- DThe lowest oxide contains metal ions in their lowest oxidation states, favoring amphoteric behavior.
Correct answer
B. In the lowest oxide,some valence electrons of the metal atom not involved in bonding can be donated i.e.act as
Step-by-step solution
Correct Option is : (B) In the lowest oxide,some valence electrons of the metal atom not involved in bonding can be donated i.e.act as a base but metal atom in highest oxides dont have such free electrons
