MCQ
When an electron drops from a higher energy level to a low energy level, then
- ✓Energy is emitted
- BEnergy is absorbed
- CAtomic number increases
- DAtomic number decreases
✓
Answer
Correct option: A.
Energy is emitted
a
Electrons drops from higher level to lower energy level by emitting the energy in the form of packet of energy (photon).
Electrons drops from higher level to lower energy level by emitting the energy in the form of packet of energy (photon).
The emitted energy have definite wavelength which can be calculated by $E = hc / \lambda$.
Likewise, electrons jumps from lower energy level to higher energy level, by absorbing energy.
The lowest energy level that an electron exist is known as its ground state.
