Question

distance between 3 rd and 5 the orbit of hydrogen atom is​

Answer 1

Distance between the 5th and the 3rd orbits = distance of 3rd orbit – distance of second orbit from the nucleus.d 3

= z×10 −10 m 0.529×n 2=0.529×9×10 −10 md

=0.529×4×10 −10 md 3 –d 2

=0.529×5×10 −10m =2.645×10 −10 m is the distance between the 5th the 3rd orbits.

Answer 2

Answer:

Radius of Bohr orbit(Rn) = R0zn2

where R0=0.529A

For hydrogen atom,

R3=R019=9R0=4.761A

R2=R014=4R0=2.116A

R3−R2=5R0=2.645A=2.645×10−8cm

The distance between third and second Bohr orbit of hydrogen atom is 2.645×10−8 cm.
