Show Answer
Solution:
Ans. (i) According to Rutherford model electron orbiting around the nucleus, continuously radiates energy due to the acceleration; hence the atom will not remain stable.
(ii) As electron spirals inwards ats angular velocity and frequency change continuously; therefore it will emit a continuousspectrum.
