Question:  Is there a table of diatomic molecules?

Answer 1:
I always remembered the diatomics this way:
Hi Bronclif!
aka...
HI BrONClF
Hope that helps.

Answer 2:
I like that mnemonic Joe! Thanks for sharing that.
That helps remember all the HOMONUCLEAR diatomic molecules
(both atoms the same); at least, all the common ones.
However, there are also many HETERONUCLEAR diatomic molecules;
HCl, NO, CO, HF, CN...
I've never seen a complete list of diatomic molecules,
but one that comes pretty close to listing all the relatively
stable ones is Huber and Herzberg's "Spectra of Diatomic Molecules."

Answer 3:
From the best of my knowledge there is not a formal table. At the
Handbook of Chemistry and Physics are listed and periodically
updated all known inorganic compounds together with its physical
constants. So you can find there included the diatomic molecules...
But, better still... since there are rules for the formation  of
such molecules, maybe you can yourself try to settle your own Table...
And if you want to do so, you can e-mail me privately and I will
help you.
(You can find the Handbook at a good library or at your school lab.)
