It is define as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave.
Wavelength
Amplitude
Speed of light
Frequency
It states that there are only certain allowed energy states for an electron and that these are quantized.
Photoelectric effect
Quantum theory
Quanta
Photons
It contains many different colors, or wavelengths, with no gaps.
Atomic spectra
Emission spectrum
Continuous spectrum
Line spectrum
It is a model of the atom where electrons travel in defined circular orbits around the nucleus.
Rutherford's nuclear model of the atom
Orbital model of the atom
Plum-pudding model of the atom
Bohr’s atomic theory
It refers to the fundamental property of matter where, at one moment it appears like a wave, and yet at another moment it acts like a particle.
Duality of matter
Uncertainty principle
Aufbau principle
Pauli's exclusion principle
They are values that is used when describing the energy levels available to atoms and molecules
Quantum numbers
Uncertainty principle
Aufbau principle
Pauli's exclusion principle
It is also called electronic structure, the arrangement of electrons in energy levels around an atomic nucleus.
Electron configuration
Orbital diagram
Aufbau principle
Pauli's exclusion principle
It implies that it is in general not possible to predict the value of a quantity with arbitrary certainty, even if all initial conditions.
Electron configuration
Uncertainty principle
Aufbau principle
Pauli's exclusion principle
It states that, in an atom or molecule, no two electrons can have the same four electronic quantum numbers.
