Question

the energy of k shell near the nucleus is​

Answer 1

k shell has minimum energy. k shell is the innermost shell of electrons surrounding the nucleus.

Explanation:

minimum energy:

• The principle of minimum energy is essentially a restatement of the second law of thermodynamics.
• It states that for a closed system, with constant external parameters and entropy, the internal energy will decrease and approach a minimum value at equilibrium.
• An isolated system has a fixed total energy and mass.

Answer 2

The energy of k shell near the nucleus is minimum.

When an electron is placed in the lowest energy level it is in the ground state and when it moves to a higher energy level it is in the excited state.

Explanation:

Different energy levels near the nucleus are as follows

1. First energy level -K shell
2. second energy level -L shell
3. Third energy level - M shell
4. Fourth energy level - N shell

This level goes on;

• The maximum number of electrons present in the orbit is 2n²
• The k shell will have minimum energy as it is near the nucleus.
• An electron will first fill the minimum energy because the atom having the lowest energy level is most stable.
• K shell will have a maximum number of two electrons.

• L shell will have a maximum number of eight electrons.

• M shell will have a maximum number of eighteen electrons.
