Give the relationship between impact parameter and scattering angle.
The absorption transitions between the first and the fourth energy states of hydrogen atom are $3.$ The emission transitions between these states will be
As an electron makes a transition from an excited state to the ground state of a hydrogen - like atom/ion
The Rutherford $\alpha$-particle experiment shows that most of the $\alpha$-particles pass through almost unscattered while some are scattered through large angles. What information does it give about the structure of the atom
Based on which experiment did the Rutherford nuclear model come from?
The number of completely filled shells for the element ${ }_{16} S ^{32}$ is
