How does the energy of a photon emitted when the electron moves from the 3rd orbital to the 2nd orbital compare to the energy of a photon absorbed when the electron moves from the 2nd orbital to the 3rd orbital?

Answer with Explanation:

Energy of orbital

Substitute the values

J

Energy of a photon emitted when the electron moves from the 3rd orbital to the 2nd orbital=

The energy of a photon absorbed when the electron moves from the 2nd orbital to the 3rd orbital=

The energy of a photon absorbed when the electron moves from the 2nd orbital to the 3rd orbital=

Therefore, in both process the energy of absorbed photon and emitted photon are same but the process are complementary to each other.

find the surface area of the sphere to the nearest square unit. use a calculator.

tbh i don't know the answer for this question
