Atomic orbital , the letters associated with those numbers are K, L, M, N, O, ... respectively. The simplest atomic orbitals are those that are calculated for systems with a single electron, such as the hydrogen atom. An atom of any other element ionized down to a single electron is very similar to hydrogen, and the orbitals take the same form. In the Schrödinger equation for this system of one negative and one positive particle, the atomic orbitals are the eigenstates of the Hamiltonian operator for the energy. They can be obtained analytically, meaning that the resulting orbitals are products of a
How to Dismantle an Atomic Bomb announced that if those tracks were leaked online, they would release the album immediately via the iTunes Store. Several months later, the finished album was leaked online, but the band did not release it earlier, despite previous comments. In late 2004, "Mercy", an unreleased track taken from the "How to Dismantle an Atomic Bomb" sessions, surfaced on the Internet through a fan who had been given a copy of the album containing the extra track. The track is of less than standard audio quality, but managed to become a favorite on fan websites. It was cut from the final release,
