Energy rank

Natural gas is a mixture of naturally-occurring methane (CH ) with other hydrocarbons and inert gases. The 2.3 trillion cubic meters (Tcm) or 81 trillion cubic feet (Tcf) of gas marketed and consumed globally in 1997 accounted for about 24 percent of the world s primary energy, ranking third among fuels after petroleum liquids (40%) and coal (25%).

Using only a periodic table (not the values for ionization energy), rank the following sets of atoms in order of increasing ionization energy.

Rank changes also occur at higher J-values when level crossings occur. When the energy of the basis function, Z7inin, overtakes the 1E basis function energy, from below (because Bin > Bi- - ), the energy rank of the... 

Next, the B C interaction is diagonalized. The result is eight groups of B C mixed 2II levels (four e, four /, the e and / levels having identical energies and mixing coefficients), which can be denoted 2II, J, e/f, k) where k (k = 1,2,3,4) is the energy rank. The transformed basis functions are then...
