Question

Magine an atom made up of a proton and a hypothetical particle of double the mass of the electron but having the same charge as the electron. Apply the bohr atom model and consider all possible transitions of this hypothetical particle to the first excited level. The longest wavelength photon that will be emitted has wavelength (given in terms of rydberg constant r for the hydrogen atom) equal to

Answer 1

having valency is 1 because it can charge the electrons

Answer 2

ANSWER:

$\lambda_{\max }=185 \mathrm{R}$

EXPLANATION:

Energy is related to mass

$\mathrm{E}_{\mathrm{n}} \propto \mathrm{m}$

The longest wavelength λmax photon will correspond to the transition of particle from n=3 to n=2

$\frac{1}{\lambda_{\max }}=2 R(122-132)$

$\lambda_{\max }=185 \mathrm{R}$

Neils Bohr is a scientist who proposed the Bohr atom model. In his theory, he assumes the electrons and nucleus as the planets which are revolving in their orbitals. His theory is based on the solar system.
