Question

What happens when an electron makes transition from higher energy level to a lower energy levels ​

Answer 1

Answer:

The median class of the following data is:

Marks 0 – 10 10 – 20 20 – 30 30 – 40 40 – 50 50 – 60

No. of students 8 10 12 22 30 18

(a) 20 – 30 (b) 30 – 40 (c) 40 – 50 (d) 50 – 60

Answer 2

Answer:

When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
