Energy is a fundamental quantity that every physical system possesses; it allows us to predict how much work the system could be made to do, or how much heat it can exchange.
In the past, energy was discussed in terms of easily observable effects it has on the properties of...

 Chapter I. Introduction | Atomic Energy for Military Purposes (The Smyth Report) | Historical Documents | ...
This binding energy, B, is the difference between the true nuclear mass, M, and the sum of the masses of all the protons and neutrons in the nucleus.
First we assumed that mass and energy were equivalent; now we are assuming that atomic nuclei can be rearranged with a consequent reduction in their total mass, thereby releasing energy which can then be put to use.
In the nuclear reactions we have described this is not generally true; neither the energy released nor the new particles formed are sufficient to maintain the reaction.

 AllRefer.com - Atomic Energy Commission (U.S. Government) - Encyclopedia
The act provided for a five-member commission appointed by the President with the advice and consent of the Senate, as well as a military liaison committee which the AEC was directed to advise and consult with on all atomic energy matters that related to military applications.
The AEC became the center of a nation-wide controversy in 1954 as a result of Oppenheimer's suspension (1953) as a consultant to the commission on the alleged grounds that he was a security risk.
Although the bulk of the AEC's work was in the field of atomic weaponry, it was also involved in projects relating to the peaceful uses of atomic energy (e.g., the development of atomic power plants for the production of electricity).

 MSN Encarta - Atomic Energy Commission
Atomic Energy Commission (AEC), civilian agency of the United States government established by the Atomic Energy Act of 1946 to administer and regulate the production and use of atomic power.
The most important goal of the 1946 act, however, was to put the immense power and possibilities of atomic energy under civilian control, although nuclear materials and facilities remained in government hands.
Under the Energy Reorganization Act of October 1974, the AEC was abolished, and two new federal agencies were established to administer and regulate atomic-energy activities: the Energy Research and Development Administration and the Nuclear Regulatory Commission.

 Hund's Rules for Atomic Energy Levels
Though often called by the name spin-spin interaction, the origin of the energy difference is in the coulomb repulsion of the electrons.
Note that the energies we are discussing here are electric potential energies, so that a negative electron in the vicinity of a positive nucleus will have a negative energy leading to a bound state.
These influences on the atomic electron energy levels is sometimes called the orbit-orbit interaction.

The terms "atomic energy" and "special nuclear material" are defined in Section 11 of the Act (42 U.S.C. Sections 151(c) and 151(d) (42 U.S.C. 2181(c) and (d)) set up categories of pending applications relating to atomic energy that must be brought to the attention of the Department of Energy.
All applications received in the U.S. Patent and Trademark Office are screened by Technology Center (TC) work group 3640 personnel, under 37 CFR *>1.14(d)<, in order for the *>Director< to fulfill his or her responsibilities under section 151(d) (42 U.S.C. 2181(d)>)< of the Atomic Energy Act.
Papers subsequently added must be inspected promptly by the examiner when received to determine whether the application has been amended to relate to atomic energy and those so related must be promptly forwarded to Licensing and Review in TC work group 3640.

 Atomic Energy Levels
If you have two electrons, then the state in which their spins are parallel (S=1, triplet state) will be lower in energy than the state in which their spins are antiparallel (S=0, singlet state).
This result is correlated with the fact that the two electrons are identical fermions, and a wavefunction which describes the pair must be antisymmetric with respect to exchange of the electrons (a requirement of the Pauli exclusion principle).
The fact that such electron configurations have lower energy means that they will be filled first, and this fact is noted in "Hund's rule #2".

 Atomic Energy levels
Further, it is usual to express level energies in terms of excitation energy instead of the usual binding energy which would be a negative quantity: Excitation energy is binding energy plus the energy of ionization (the energy required to remove an electron from the most tightly bound level to infinity, the ionization potential).
The n=1 level with the hash marks is the zero excitation energy level, the most tightly bound state of H. We call this the ground level and any atomic transitions that involve the ground level are called resonance lines.
Transitions can occur between continuum states with any energy and are called free-free or Bremsstrahlung transitions and represent a change in the speed of the electron relative to the proton.
