➡Rutherford 's Atomic Model ⬅
-------------------------------------------------------------------------------------------------------


◾The main drawback was that he couldn't explain the stability of an Atom;
----------------------------------------------------------------------------------------------------

✔According to him, the electrons revolve around the nucleus in very high speed . But we know anything that revolves will also radiate Energy , and once that energy will finish. Then , the electron would fall in to the Nucleus. This was the reason why his model failed..

◾Z [ Atomic Number ] = 4

◾Configuration = K [ 2 ] , L [ 2 ]

✔Valency = 2

✔Element is Beryllium.
