Spectral line energy

Postby Jane Burgan 1C » Wed Oct 10, 2018 6:15 pm

When an electron drops from a higher energy level to a lower energy level, why isn't the energy given off positive? Why is negative? Because wouldn't it have extra energy that can be given off now that it's going down?

I think it's negative because we are viewing the energy relative to the electron. So, the electron is losing energy, thus the change in energy is negative.
