they move closer to the atomic nucleus.

they move farther from the atomic nucleus.

they release their energy.

Explanation:

When fluorescence occurs in chlorophyll, electrons first absorb energy and move to a higher - energy state (farther from the atomic nucleus). Then, as they return to a lower - energy state, they release their energy in the form of light (fluorescence).

They move farther from the atomic nucleus.
They release their energy.
