Question

Imagine an atom made up of a proton and a hypothetical particle of double the mass of electron but having the same charge as the electron. Apply bohr atom model and consider all possible transition of this

Answer 1

Answer:

Energy is related to mass:

En x m

The largest wavelength λmax photon will correspond to the transition of particle from n = 3 to first excited state, n = 2 .

1/λmax= 2R(1/2²-1/3²)

1/λmax=5R/18

>>λmin=18/5R
