Each energy level is labeled with the quantum number n (n=1, 2, 3,...) and the energy of a particular level can be determined by the following: En=-Rh (1/n^2). This is where Rh is the Rydberg constant of the element. For the simplest atom, the hydrogen atom, Rh=2.18*10^-18 J.
This article is about energy per unit volume. For energy per unit mass or energy density of foods, see specific energy. Energy density is the amount of energy stored in a given system or region of space per unit volume or mass, though the latter is more accurately termed specific energy.he higher the energy density of the fuel, the more energy may be stored or transported for the same amount of volume. The energy density of a fuel per unit mass is called the specific energy of that fuel.
