Chemistry

Azimuthal Quantum Number

Species the shape of the orbital and it is called as subshell

Principal Quantum Number

Specifies the energy of the electron and size of the shell

Quantum Numbers

Set of four numbers to represent size, shape, orientation and energy of orbits and spin of the electron

Orbitals

Regions around the nucleus where the probability of finding electrons are maximum

Heisenberg Uncertainty Principle

It is impossible to measure simultaneously both the position and momentum with accuracy for microscopic particles

Plank’s Quantum Theory

Radiant energy emitted is in the form of small energy packets called quantum or photon

Electromagnetic Spectrum

Arrangement of electromagnetic radiations in the increasing order of wavelengths

Isosters

Molecules having same number of atoms and same number of electrons

Isoelectronic

Atoms, Molecules and Ions having same number of electrons

Isotones

Atoms having same number of neutrons but different mass numbers
