Question

Write general oxidation state of Lanthanoids.

Answer 1

Answer:

Lanthanides show variable oxidation states. They also show +2, +3, and +4 oxidation states. But the most stable oxidation state of Lanthanides is +3. Elements in other states hence try to lose or gain electrons to get +3 state.

PLzzzzzz. mark it as brainliest...........

Answer 2

The most common and stable oxidation state of Lanthanides is +3. It is attained by removing outermost 2 electrons of 6s electrons and 1 electron from 4f electrons.
