Ground State Question

Postby Helen Mejia 1I » Fri Oct 19, 2018 7:40 pm

What does it mean for an electron configuration to be in ground state? Can someone give an example?

The ground state means that the electrons are in their lowest energy state.

For example, this is a Carbon atom's electron configuration. This is the ground state because all the lower energy orbitals (1s and 2s) are occupied by an electron.

Let's say that an electron absorbs some discrete energy quantity that excites it into the next orbital. This is an excited state because the electrons have higher energy and there's an open spot for an electron in the 2s orbital
