Question

Determine the de-Broglie wavelength associated with an electron in the 3rd Bohr's orbit of He+ ion

Answer 1

Answer:

mass of He+=4 as before because the no. of electron is change where the atomic mass do not change

wavelength=h/me

v=0.529×n2/z

v= 2.38

=6.66*10^-34/2.38

=...

so that's all

hope so helpful..
