Notice that the probability density for an energy eigenfunction is independent of time: Ψ(x,t)2=Ψ∗(x,t)Ψ(x,t)=ψ∗(x)eiωtψ(x)e−iωt=ψ(x)2.(7.11) Thus, energy eigenfunctions are called stationary states.

The ground state energy level of the electron in a hydrogen atom is −13.6 eV, which is equivalent to an ultraviolet photon of roughly 91 nm wavelength.. The energy levels of hydrogen can be calculated fairly accurately using the Bohr model of the atom, which conceptualizes the electron as "orbiting" the proton in analogy to the Earth's orbit of the Sun. ΔG298D = −34 kJ mol−1 12.0 g H2 × 2 2 1 mol H 2.0 g H × 2 1 mol reaction 3 mol H × 34 kJ 1 mol reaction-= -68 kJ One point is earned for the correct stoichiometry. One point is earned for the correct answer. (c) Given that ΔH298D for the reaction is −92.2 kJ mol−1, which is larger, the total bond dissociation energy The energy can be released as one quantum of energy, as the electron returns to its ground state (say, from n = 5 to n = 1), or it can be released as two or more smaller quanta as the electron falls to an intermediate state, then to the ground state (say, from n = 5 to n = 4, emitting one quantum, then to n = 1, emitting a second quantum). The first ionization energy (Ei1) is the energy associated with the removal of an electron from the neutral gaseous atom. The reaction is represented for the generalized atom X as X→X^+ + e− The amount of energy required to remove an electron is related to the effective nuclear charge and the stability of the electron configuration of the atom.

Each hydrogen atom contributes one electron, and thus, H− 2 has three electrons while H+ 2 has one. Each hydrogen atom contributes one 1s atomic orbital, and thus, the orbitals overlap according to MO theory to form one σ1s and one σ* 1s MO by conservation of orbitals.
