For example, polar bears can smell food from one and a half kilometers away, and some dogs can pick up a trail that is four days old. The splitting of the levels depends on L, S, and J, leading to more than the three lines seen in the normal effect. Atomic number is the number of protons present inside the nucleus of an atom of an element. Wave number of particle is the spatial frequency of a particle, measured in cycles per unit distance or radians per unit distance.
