In captured form and often with bonds broken open they are called moieties.

Basic resource molecules
For mechanosynthesis of diamond ethyne C2H2 methane CH4 and traces of digermane Ge2H6 can be used. This has been toroughly analyzed.
Further molecules of prime interest are carbon dioxide CO2 water H2O and nitrogen gas N2. The capability of handling those allows for tapping the air as a resource for products that (almost) exclusively contain diamondoid molecular elements out of hydrogen carbon oxygen and nitrogen (HCON).
From the metals Aluminum and Titanium would be of interest.
Resource molecules for other elements
They should preferentially be non or at least low toxic and easy to handle.
- for boron: B2H6 diborane is toxic and reacts with water to
B(OH)3 boric acid which is pretty harmless and thus a better resource - for fluorine: SF6 sulfur hexafluoride very heavy pretty inert gas, soluble in ethanol
the sulfur can be used or disposed as diluted sulfuric acid - for aluminum: ?
- for silicon: silicic acid self polymerizes and is thus not suitable
SiH4 [1] seems better but it's quite toxic, higher silans tend to be explosive - for chlorine: dissolved table salt NaCl - or diluted hydrochloric acid
Sources for phosphorus
- for phosphorus: PH3 phosphine seems too toxic
H3O4P phosphoric acid seems good - ammonium phosphate compounds - (wikipedia)
Sources for sulfur
Good information resource for sulfur compounds: wikipedia
of main interest
- ammonium sulfate (NH4)2SO4 (wikipedia) - pro: waste nitrogen can go to atmosphere, massively available - con: explosive in dry form
- methylsulfonylmethane C2H6O2S- (wikipedia) - pro: non toxic - con: carries carbon too
- sulfuric acid H2SO4 (wikipedia) - pro: massively available - con: acidity
maybe interesting
- diallyl trisulfide C6H10S3 (wikipedia) - main component of garlic oil - con: carries lots of carbon and hydrogen
- syn-Propanethial-S-oxide C3H6OS (wikipedia) - irritant expelled by cut onions
- dimethyl trisulfide C2H6S3 (wikipedia)
- carbon disulfide CS2 (wikipedia) - soluble in ethanol - pro: massively available - con: toxic
- carbonyl sulfide (wikipedia) - con: toxic, carries less sulfur than carbon disulfide
- hydrogen sulfide H2S, sulfur dioxide SO2, sulfur trioxide SO3 - all too dangerous and toxic
- thioacetic acid C2H4OS (wikipedia)
- methanesulfonic acid CH3SO3H (wikipedia), (wikipedia)
Notes
If the non metal element in question is poisonous or unstable with the bonds just capped with hydrogen the oxygen acids of the element may be a better choice. To reduce acidity but not introduce metal cations that would in many cases remain as waste the ammonium cation (wikipedia) can be used.
