What are the Defects of Bohr’s Atomic Model? In 1913 Neil Bohr’s presented a new model for an atom, known as Bohr’s atomic model. Niels Bohr model describes an atom as a small positively charged nucleus surrounded by electrons that travel in circular orbits around the positively charged nucleus like planets around the sun in …

Electronic Configuration: The distribution and arrangement of electrons in various shells, sub-shells and orbitals is called electronic configuration. Electronic configuration follows three rules. Auf Bau Principle: It states: “Electrons occupy shells in increasing order of their energies” or “Electrons occupy sub-shells in increasing order of their energies or n+ℓ values” First electrons fill the sub-shell with …

Shell, Subshell and Orbital Shells By “shell,” we simply mean the path taken by electrons as they orbit the nucleus of an atom. A shell of electrons can be visualised as an orbit around the nucleus of an atom. Because each shell can only accommodate a given number of electrons, each shell is connected with …
