Question

What is the change in the orbit radius when the electron
in the hydrogen atom (Bohr model) undergoes the first
Paschen transition?
Give me explanation ❤❤​

Answer 1

Answer:

as per the bhor model radius if hydrogen model can be given as

r=0.05n^2/Z where r is in 'nm'

and for the first paschen transition

electron changed its position from n=3 to n=4 during excitation nd vice versa during de-excitation

now since uts hydrogen atom Z=1

so put the value in the corresponding formula to find the radius of correspinding orbitals nd find the differnce btwn corresponding values of radii

Answer 2

As per Bohr's model, radius of hydrogen like atoms can be given as, r = 0.05 n^2/Z , where r is in 'nm'. And for first paschen transition, electron changes its position from n=3 to n=4 during excitation and vice versa during de-excitation
