Answer:
The first shell contains 2 electrons
second shell contains 4 electron
third shell contains 8 electrons
Step-by-step explanation:
Electrons rotate around the nucleus in one or more orbits/energy levels.
The maximum number of electrons in one energy level is 2n2
For example, In shell K, energy level is 1, maximum number of electrons can be 2 × (1) ² = 2
The outermost shell cannot have more than 18 electrons.
A new shell cannot be started until the previous one has reached its maximum limit.
