Question

name different shells or energy levels of an atom.​

Answer 1

Answer:

Electrons orbit the nucleus of an atom at different ranges, called shells.

Each shell has a different energy level, increasing the further it is from the nucleus.

 

Each energy level is given a number called the principal quantum number, n. The closest shell has a value of n=1. The next shell has a value of n=2, etc.

 

The maximum number of electrons possible in the first four energy levels are:

 

n=             Shell                 Maximum Number of Electrons

1                 1st Shell                                      2

2                   2nd Shell                                 8

3                 3rd Shell                                         18

4                  4th Shell                                 32
