It states that no electron pairing takes place in the p, d and f orbitals until all the orbitals of the given sub-shell contain 1 electron each with parallel spins.
Quantum numbers: These are numbers which are used to specify the location and energy of an electron and size, shape and orientation of the orbital to which a particular electron belongs. Principal or total quantum number (n): This quantum number is identical with that used in Bohr Sommer field theory. It can have only non
Nature of light and electromagnetic spectrum: According to Newton’s corpuscular theory, light is propagated as a stream of particles, called corpuscles. This could justify the phenomenon of reflection and refraction of light but failed to explain the phenomenon of diffraction, interference etc. Clerk Maxwell suggested that light waves are associated with both electric and magnetic
