Text Solution
Verified by ExpertsB
True, atom of each element emits characteristic spectrum.
True, according to Bohr's Postulate, 
and hence electron resides into orbits of specific radius called stationary orbits.
False, densityof nucleus is constant.
False, a free neutron is unstable, decays into proton and electron and antineutrino.
(E) True, ustable nucleus shows radioactivity.
