Which of the following elements DO NOT react directly with nitrogen to form nitride -
Options:(select one or more)
Answer:
A, C, D
Solution:
Among alkali metals, only lithium (Li) reacts directly with nitrogen to form a stable nitride Li₃N.
Sodium (Na), Potassium (K) and Rubidium (Rb) do not react directly with nitrogen under normal conditions to form nitrides.
This is because Li⁺ is very small and has high lattice energy, making Li₃N stable.
Therefore, Na, K and Rb do not form nitrides directly.
