bound electrons

Postby FrankieClarke2C » Thu Oct 11, 2018 4:14 pm

On the board it was stated that a negative sign means bound e- has lower energy than free e-. What is meant by "bound electron" vs "free electron"

A bound electron is one that is still considered part of the atom and is attracted to the nucleus whereas a free electron is one that absorbed enough energy from photons to completely leave the atom.

A bound electron can be an electron in the energy state n=1, the grounded state. A bound electron is still relatively close to the nucleus. Whereas an energy state of n=4 is farther away from the nucleus. The farther away from a nucleus an electron is, the higher energy state it's at.
