Question

What amount of energy is needed for an electron to jump from n = 1 to n = 4?

Answer 1

`E=2.04* 10^(-18)\ J`

Step-by-step explanation:

We need to find the energy for an electron to jump from n = 1 to n = 4.

The energy in transition from 1 state to another is given by :

`E=(-2.18* 10^(-18))/(n^2)\ J`

The difference in energy for n = 1 to n = 4 is:

`E=-2.18* 10^(-18)* ((1)/(4^2)-1)\\\\E=2.04* 10^(-18)\ J`

So, the required energy is equal to
`2.04* 10^(-18)\ J`.
