Account for the following:
Eu2+ with electronic configuration [Xe]4f76s2 is a strong reducing agent.
Advertisements
उत्तर
Because it is more stable than Eu, Eu2+ is a powerful reducing agent. After removing two electrons, the electronic configuration is 4f76s2, resulting in a half-filled (f) electronic configuration that acts as a strong reducing agent.
