Question

Transportation elements from coloured compound.explain

Answer 1

Answer:

transition elements form coloured compound because of DD transition and ff transition because when are suitable amount of light and frequency fall on it there is a transition of electron lower energy higher energy and then back to low energy and due to which electrons EMIT light of adequate frequency which corresponds to a colour and phenomena do not occur in s and p block elements because for such transactions higher energy is required in case of s orbital and p orbital
