Front

What does the notation '1s² 2s² 2p⁶' represent?

Back

It represents the electron configuration of an atom, indicating the distribution of electrons among the various atomic orbitals.

Front

What is the ground state of an electron?

Front

What is the difference between excited state and ground state?

Back

In the excited state, an electron has absorbed energy and moved to a higher energy level, while in the ground state, it is in its lowest energy configuration.
