Question

The life time of electron in the metastable
state is in the order of​

Answer 1

Answer:

Metastable state is an excited state of an atom or other system with a longer lifetime than the other excited states. However, it has a shorter lifetime than the stable ground state. Atoms in the metastable state remain excited for a considerable time in the order of 10-6 to 10-3.

Answer 2

Life time of electron:

Explanation:

Electron:

• Electron, lightest stable particle known. Under ordinary conditions electrons are sure to the charged nuclei of atoms by the attraction between opposite electric charges. in a very neutral atom the amount of electrons is the image of the amount of positive charges on the nucleus.

       Metastable state:

• Metastable state is an excited state of an atom or other system with a extended lifetime than the opposite excited states. However, it's a shorter lifetime than the stable state.
• Atoms within the metastable remain excited for a substantial time so as of $10^-^3s$.
