- Homework Statement
- i'am trying to find the volume of the nucleus to the volume of the electron (for hydrogen )

- Relevant Equations
- R = R. A^1/3 the radius of the nucleus

re = 2.8 * 10^-15 m

i'am trying to find the ratio between the volume of the nucleus for the hydrogen atom to its electron , but when i try to use the previous equations it seems wrong as i'am getting a low number like if the electron is bigger .

i used the the classical electron radius as it was the only thing that i could find :

and the radius of the nucleus is obtained from the equation:

R = R

now the radius of the electron is bigger ?!

is this equation not valid for small atoms like hydrogen ?

is there any other approach for the problem ?

_{o}A^{1/3}and as R_{o}= 1.2 * 10^{-15}mnow the radius of the electron is bigger ?!

is this equation not valid for small atoms like hydrogen ?
