Question

Explain the following terms.
A) Ground state
B) Excited state. ​

Answer 1

Answer:

The ground state configuration is the lowest energy, most stable arrangement. An excited state configuration is a higher energy arrangement. If you see electrons have been "moved" to a higher orbital before filling the lower orbital, then that atom is in an excited state.

Answer 2

Answer:

The groud state:- The ground state of a quantum-mechanical system is its lowest-energy state; the energy of the ground state is known as the zero-point energy of the system. An excited state is any state with energy greater than the ground state.

Excited state:- In quantum mechanics, an excited state of a system (such as an atom, molecule or nucleus) is any quantum state of the system that has a higher energy than the ground state (that is, more energy than the absolute minimum). Excitation is an elevation in energy level above an arbitrary baseline energy state.
