Solution
The energy of the electron in hydrogen-like atom in nth orbit is
 
 

We have
 
 
rydberg.
The ionization energy
 
 

 
 

 
 

a. The energy required to excite the electron from
 
 
to
 
 
is given by
 
 

 
 

 
 

 
 

If
 
 
is the wavelength of radiation emitted , then
 
 
, i.e.
 
 

 
 

 
 

b. Radius of first Bohr orbit
 
 

 
 

 
 

2.5 xx 10^(-11) m
