Question

calculate the time taken by the electron to complete 10 revolutions in first orbit of thd hydrogen atom
​

Answer 1

Answer:

Time taken for an electron to complete one revolution in Bohr orbit of hydrogen atom is : t=distance/velocity

Distance of Bohr orbit = circumference of Bohr orbit = 2πr

t=

v

2πr

Since mvr=

2π

nh

v=

2πmr

nh

Thus, t=2πr×

nh

2πmr

t=

nh

4π

2

mr

2

Answer 2

Answer:

This is the time taken on the electron to complete 10 revolutions in first orbit of the the hydrogen atom
