The dissociation energy of the molecule is 1.33 eV . Ionization potential is around 7.9 eV with the MgH + ion formed when the molecule loses an electron.

Where the temperature is much higher than ionization potential, the matter exists in the form of recombination, when the expanding Universe cooled enough to allow electrons to become attached to nuclei.
43.
Lower in the atmosphere all of the solar photons with energies above the ionization potential of N 2 and O 2 have already been absorbed by the higher layers and thus no appreciable ionization occurs.
44.
The most obvious effect is that the sum of the first three ionization potentials of gallium is higher than that of aluminium, whereas the trend in the group would be for it to be lower.
45.
The three parameters defining B3LYP have been taken without modification from Becke's original fitting of the analogous B3PW91 functional to a set of atomization energies, ionization potentials, proton affinities, and total atomic energies.
46.
Since the frequency of the emitted radiation depends on both the kinetic energy and on the ionization potential, the different frequencies are emitted at different recombination time ( i . e . the emitted pulse is chirped ).
47.
With their closed valence shells, the noble gases have the highest first ionization potentials in each of their periods, and feeble interatomic forces of attraction, with the latter property resulting in very low melting and boiling points.
48.
The hot filament reaches a temperature of less than 2500 degrees Celsius, leading to the inability to create atomic ions of species with a high ionization potential, such as Osmium ( Os ), and Tungsten ( Hf-W ).

The ionization potential of dubnium in its maximum oxidation state should be slightly lower than that of tantalum and the ionic radius of dubnium should increase compared to tantalum; this has a significant effect on dubnium's chemistry ( see below ).
50.
The low thermal conductivity minimizes thermal losses in the lamp while in the operating state, and the low ionization potential causes the breakdown voltage of the gas to be relatively low in the cold state, which allows the lamp to be easily started.
