Average lifetime of a hydrogen atom excited to n = 2 state is 10 –8 s. Find the number of revolutions made by the electron on the average before it jumps to the ground state.

Question

Philoid · Accepted Answer

As we know that number of revolution is equal to average lifetime divided by time period. So first we calculate time period.

Now, from Bohr’s model we can say that

Where n=2, m= and h

Time period

Number of revolution

Average lifetime of a hydrogen atom excited to n = 2 state is 10–8 s. Find the number of revolutions made by the electron on the average before it jumps to the ground state.

Average lifetime of a hydrogen atom excited to n = 2 state is 10^–8 s. Find the number of revolutions made by the electron on the average before it jumps to the ground state.
