What is Crystal Field Theory?
Crystal Field Theory (CFT) is a model used to explain the electronic structure of complex metal ions in crystals. It describes how the electrostatic interaction between the metal ion and the surrounding ligand (non-metal) i
Work:
Work is said to be done when a force applied on the body displaces the body through a certain distance in the direction of force.
