1.	According to Bohr's theory , the electrons revolve round the nucleus in definite paths called orbits . Do the electrons revolve round with same speed in all orbits? Justify.
Answer» Solution :The electrons revolve round the nucleus at high speed in the ORBITS in ORDER to counterbalance the nuclear forces of attraction. As nuclear force of attraction decreases with increase in distance from the nucleus , the nuclear force fo attraction on the electrons decreases. Therefore, electron revolves round with lesser velocity to overcome lesser nuclear force of attraction . THUS, hte veolcity of electron in orbits decreases in the order `K gt L gt M gt N`
