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).…

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…
