Hydrogen Electron Orbitals I.
Hydrogen accounts for about 74 percent of the normal matter in the Universe. This visualization shows the electron clouds of hydrogen through the probability density function when the principal quantum number, N, is between 1 and 4. The probability density illustrates where the electron is most likely to be found if measured, red indicates high probability, blue indicates low probability.
