Mendelevium - 101Md: properties of compounds

The bond energy in the gaseous diatomic species MdMd is (no data) kJ mol-1.

Mendelevium: bond enthalpies in gaseous diatomic species

The following values refer to neutral heterodiatomic molecules in the gas phase. These numbers may well differ considerably from, say, single bond energies in a solid. All values are given in kJ mol-1.

Diatomic MdX bond enthalpies. All values are quoted in kJ mol-1. Each formula in the table (MdO, MdF, and so on) is a link - select these to see visual periodicity representations for bond enthalpies involving mendelevium to elements of your choice.

Notes

I am grateful to Professor J.A. Kerr (University of Birmingham, UK) for the provision of the bond strengths of diatomic molecules data.

The values given here are at 298 K. All values are quoted in kJ mol-1. Generally, these data were obtained by spectroscopic or mass spectrometric means. You should consult reference 1 for further details. A note of caution: the strength of, say, the C-H bond in the gaseous diatomic species CH (not an isolable species) is not necessarily, the same as the strength of a C-H bond in, say, methane.

The strongest bond for a diatomic species is that of carbon monoxide, CO (1076.5 ± 0.4 kJ mol-1). The strongest bond for a homonuclear diatomic species is that of dinitrogen, N2 (945.33 ± 0.59 kJ mol-1).
