Taking Bohr's radius as \(r_0=53\,\text{pm}\), the ground state radius of \(Li^{2+}\) ion, on the basis of Bohr's model, will be about

According to Bohr's model of the hydrogen atom, (A) the radius of the orbit of an electron is directly proportional to \(n\). (B) the speed of the orbiting electron is directly proportional to \(\dfrac{1}{n}\). (C) the total energy of the electron is directly proportional to \(\dfrac{1}{n^2}\). (D) the radius of the orbit of an electron is directly proportional to \(n^2\). Choose the correct answer from the options given below:

In terms of Bohr radius \(a_0\), the radius of \(2^{nd}\) Bohr orbit of Hydrogen is:

In a hydrogen atom an electron makes a transition from \(n_1 \rightarrow n_2\), where \(n_1\) and \(n_2\) are the principal quantum numbers of these two states. Assuming Bohr's model to be valid, if the time period of electron in the initial state is eight times of that in the final state, the possible values of \(n_1\) and \(n_2\) are:

The frequency of revolution of the electron in Bohr's orbit varies with \(n\), the principal quantum number as

An electron in the ground state of a hydrogen atom absorbs 12.09 eV energy. The angular momentum of the electron increases by
