Flame Test

When heat is applied to the atoms that make up the material, some electrons have high energy levels and then fall to the lower levels. Some electrons emit as much energy as the energy level difference. By measuring the emitted…

Bohr’s Atomic Model

In 1913, Niels Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus. The atom only has certain energy levels, they are determined by fixed circular orbits of electrons around…

Electron Configuration of an Atom

Electron Configuration is the arrangement of electrons in an atom. Electrons fill the lowest energy level first. The atomic numbers tells how far electrons are from the nucleus. And then, what other rules are there?

Matter Wave and de Broglie’s Atomic Model

Light has both particle and wave properties at the same time. Likewise, de Broglie (France, 1892 – 1987) thought that such things as electrons which had so far been considered to be particles might possess wave nature as well (1932).…

Quantum of Light

This simulation assumes a situation where all of the energy emitted from the candle is emitted as light of a certain wavelength. The power of the candle is assumed to be 50W. The emitted light wave is for the sake…

수소 원자의 스펙트럼 Spectrum of Hydrogen Atom

Spectrum of Hydrogen Atom

When the energy is given to the eletron by heating it, for example the electron is promoted to a higher energy level. This state is unstable and temporary. When the electron falls back to a lower level. The energy difference…
