Question

.If an orbiting electron falls to a lower orbit, the total
energy of that atom will be
a. increase
b. decrease
c. remain same
d. None of above​

Answer 1

Answer:

If an orbiting electron falls to a lower orbit, the total

energy of that atom will be decrease

Explanation:

• Decreased Kinetic Energy demotes an Electron to a lower orbit
• This is called an excited state. An electron in an excited state can release energy and 'fall' to a lower state. When it does, the electron releases a photon of electromagnetic energy. The energy contained in that photon corresponds to the difference between the two states the electron moves between
• When an electron jumps from lower orbit the energy of the electron decrease. The extra energy required for the electron to go from lower orbit to the higher orbit should be supplied.
