... Quantum numbers are used to describe atomic orbitals and the electrons in them. There are 4 quantum numbers: o The principal quantum number (n), indicates the main energy level occupied by the electron. n = a whole number such as 1, 2, 3, 4 n tells the distance from the nucleus and the energy of ...

It also explains the movement of electrons to lower energy levels when the source of energy has disappeared. Accompanying this drop in energy level is the emission of electromagnetic radiation (light as one ...

Hydrogen atom
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the elemental (baryonic) mass of the universe.In everyday life on Earth, isolated hydrogen atoms (usually called ""atomic hydrogen"" or, more precisely, ""monatomic hydrogen"") are extremely rare. Instead, hydrogen tends to combine with other atoms in compounds, or with itself to form ordinary (diatomic) hydrogen gas, H2. ""Atomic hydrogen"" and ""hydrogen atom"" in ordinary English use have overlapping, yet distinct, meanings. For example, a water molecule contains two hydrogen atoms, but does not contain atomic hydrogen (which would refer to isolated hydrogen atoms).
