List of top Chemistry Questions on Bohr’s Model for Hydrogen Atom asked in KCET

The ionisation energy of an electron in the ground state of helium atom is $24.6\, eV$. The energy required to remove both the electron is

The ionization energy of $Li^{2+}$ is equal to

An electron in hydrogen atom makes a transition $n_1 \rightarrow n_2$ where $n_1$, and $n_2$ are principal quantum numbers of the two states. Assuming Bohr?? model to be valid, the time period of the electron in the initial state is eight times that in the final state. The possible
