Question

whether all shells in atom posses same energy.Explain?​

Answer 1

$\huge{\underline{\underline{\boxed{\sf{\purple{Answer ࿐}}}}}}$

Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. As you go farther from the nucleus, electrons at higher energy levels have more energy.

Answer 2

Answer:

No.

Explanation:

Because electrons are minuscule compared with protons and neutrons, the number of protons plus neutrons gives the atom its atomic mass. All atoms of a given element always have the same number of protons, but may differ in the number of neutrons found in the nucleus.
