Rutherford’s $\alpha$-particle experiment showed that the atoms have
Proton
Nucleus
Neutron
Electrons
The transition from the state $n = 3$ to $n = 1$ in a hydrogen like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition from
What is head-on collision ? For that tell the impact parameter.
Based on which experiment did the Rutherford nuclear model come from?
In a hydrogen atom, the electron is in $n^{th}$ excited state. It may come down to second excited state by emitting ten different wavelengths. What is the value of $n$ :
According to the Rutherford’s atomic model, the electrons inside the atom are
