An electron of hydrogen is replaced by a particle of mass 247 times and having same charge. Find the energy to ionise it.

If electron of hydrogen atom is replaced by another particle of same charge but of double mass then:

Define ionization energy. How would the ionization energy change when electron in hydrogen atom is replaced by a particle 200 times heavier than electron, but having the same charge?

In a Bohr atom the electron is replaced by a particle of mass 150 times the mass of the electron and the same charge. If a_(0) is the radius of the first Bohr's orbit of the orbital atom, then that of the new will be .

In a hydrogen atom, if the electron is replaced by a particle which is 200 times heavier but has the same charge, how would its radius change?

Imagine that the electron in a hydrogen atom is replaced by a muon (mu) . The mass of Muon particle is 207 times that of an electon and charge is equal to the charge of an electron. The ionization potential of this hydrogen atom will be:

In Thomson experiment of finding e//m for electrons, been of electron is replaced by that of muons (particle with same charges as of electrons but mass 208 times that of electrons). No deflection condition in this case satisfied if

A particle having no charge and no mass is
