Differentiate between Shell, Sub-shell and Orbital Video Lecture


Shell is the path taken by electrons around the nucleus of an atom.


The subshell is the path an electron follows within a shell.


The orbital function depicts the wavelike behaviour of an electron.

Atoms are made up of electrons, protons, and neutrons. In the nucleus, protons and neutrons are present. A cloud of electrons surrounds the nucleus. This electron cloud contains electrons in continual motion. Additional research has revealed that this is not only a cloud. Electrons progress along quantized energy levels. They resemble routes for electron movement. These paths are characterised by the terminology shells, subshells, and orbitals. Shells are formed of electrons with the same primary quantum number and subshells are composed of electrons with the same angular momentum quantum number, whereas orbitals are composed of electrons with the same energy level but different spins.
