Difference between Ground state and Excited state
Ground state |
Excited state |
The electron in a system are in the lowest energy level this state is known as ground state. | Any state of the system which have higher energy level than ground state is known as excited state. |
Ground state has long lifetime. | Excited state has short lifetime. |
It has to be zero energy. | It has high energy. |
The distance between atomic nucleus and ground state electron is least possible. | The distance between atomic nucleus and excited state electron is higher. |
It is highly stable. | It is highly unstable. |
In this state electron located in low energy level. | In this state electron located In high energy level. |
