What is the ratio of radii of the orbits corresponding to first excited state and ground state in a hydrogen atom? |
|
Answer» Solution :We knowthat radius of nith orbit in a hydrogen atom is GIVEN by `r_(N) = r_(0)n^(2)`, where `r_(0)` = radiusof orbitin stablein stablestatecorrespondington = 1 . `THEREFORE `radiusof hydrogenorbitin firstexcitedstate`(n = 2) r_(2) = r_(0) (2)^(2) = 4r_(0)` `rArr "" (r_(2))/(r_(1)) =(r_(2))/(r_(0))= (4)/(1)` |
