State any two Bohr’s postulates and write the energy value of the ground state of the hydrogen atom.
The energy associated with the first orbit of He+ is ____________ J.
Hydrogen atom has only one electron, so mutual repulsion between electrons is absent. However, in multielectron atoms mutual repulsion between the electrons is significant. How does this affect the energy of an electron in the orbitals of the same principal quantum number in multielectron atoms?
The angular momentum of electron in nth orbit is given by
How will the energy of a hydrogen atom change if n increases from 1 to ∞?
Given below are two statements:
Statements I: According to Bohr's model of an atom, qualitatively the magnitude of velocity of electron increases with decrease in positive charges on the nucleus as there is no strong hold on the electron by the nucleus.
Statement II: According to Bohr's model of an atom, qualitatively the magnitude of velocity of electron increase with a decrease in principal quantum number.
In light of the above statements, choose the most appropriate answer from the options given below:
If a revolving electron emitted radiation continuously, what would equal the frequency of emitted radiation?
