Chemical element
From apm
This page is about the possible usage of elements in advanced atomically precise technology. Predominantly in the context of usage as structural building material in compounded form to various nonmetals forming gemstones. If you seek the general definition for what a chemical element is please consult Wikipedia or other sources.

Metals
Metals in pure or alloyed form can be problematic for use in advanced productive nanosystems.
For existing examples how metals atoms can be integrated such that bonds stay sufficiently covalent in character one can look into:
- Gemstones (See: Gemstone like compound)
- Metal complexes
Special seldom elements
- Germanium Ge (very useful for mechanosynthesis)
- seldom halides: Iodine and Bromine I Br
- seldom stable chalkogenides: Selenium and Tellurium Se Te
- seldom pnictogenides: Arsenic Antimony and Bismuth As Sb Bi (bismuth so little radioactive that it can be considered stable)
- most precious metals: Gold Iridium Indium Au Ir In
- seldom heavy metals: Osmium Os ...
- less common rare earth elements: ...
