Assuming the validity of Bohr's atomic model for hydrogen like ions the radius of 
ion in its ground state is given by 
, where 
_______ (Where 
is the first Bohr's radius.)
Text Solution
Verified by ExpertsD
The radius of a hydrogen-like ion according to Bohr's atomic model is given by the formula:
Where: 
is the first Bohr radius ( 
)
represents the principal quantum number
is the atomic number of the ion
For the ion 
, the atomic number 
and we are considering the ground state, so 
.
Plugging these values into the formula, we get:
This shows that the radius of 
in its ground state is 
, meaning 
.
