Question

define resonance.. ...​

Answer 1

ANSWER

✔️ There are some molecules/ions which can be represented by a number of different ways structures but none of these structures can explain the actual properties of molecules/ions. The different Lewis structures are called resonating structures. The actual structure is a mixture of all these resonating forms and is called resonance hybrid.

Answer 2

Answer:

It is a special case of forced vibrations when the natural frequency of the vibrating body is exactly equal to the frequency of the external periodic force applied on the body. such vibrations are called resonant vibrations mother bodies which possess such vibrations are called resonating bodies.
