What is the difference between electron shells and electron orbitals?

Hint : Electrons are negatively charged atom particles. All of an atom's electrons combine to form a negative charge that balances the positive charge of the protons in the atomic nucleus. Electrons are extremely small in comparison to the rest of the atom. An electron has a mass that is nearly 1,000 times that of a proton.

Complete Step By Step Answer:
Electrons are found in clouds that surround an atom's nucleus. These clouds are organized into shells and are located at specific distances from the nucleus. Because electrons move so quickly, it's impossible to tell where they are at any given time.
Scientists discovered specific areas where electrons are likely to be found after years of experimentation. The overall shape of the shells varies depending on the number of electrons in an element. The more shells and electrons an atom has, the higher its atomic number. As you add more electrons, the overall shell shape becomes more complex (due to the suborbital).
Here is the difference between electron shells and electron orbitals,



Note :
Electrons are essential in all chemical bonds. Electrovalent bonding (ionic) is a type of bonding in which an electron from one atom is transferred to another atom. As one atom loses an electron and another gains one, you end up with two ions. The second type of bonding is covalent bonding, in which electrons are shared by two or more atoms in a cloud. Both types of bonds have specific advantages and weaknesses.
