How to portray that action of 2+ atoms : AVoid5
1 point · 2 months ago If an atom finds an affinity for an additional atom, ions and isotopic discussions can possibly confound our fifthglyth-avoiding ways. Structurally, compound atoms can call on polyatomic functionality, anionic or ionic polarization, hydrophilic or hydrophobic attraction, lipophilic or amphiphilic, hydroxyl amino acid substitutions of functional groups on carbon backings.

English chemist Smithson Tennant in 1797 proved that diamond consists of a three-dimensional crystalline array of carbon atoms -- the purest and hardest form of carbon.
When atoms are getting close | Scientist Live
As reported by the researchers in Nature Chemistry, the carbon atom and the chlorine atom in the so-called chlorotrinitromethane molecule are only 1.69 Angstroms apart from one another. "Non-covalent interactions are one of the factors responsible for this short distance", declared Göbel, whose doctoral thesis revealed the new results.
