WebApr 8, 2016 · A regular covalent bond is formed when two atoms combine orbitals with only one electron each. This gives a molecular orbital with two electrons. However, if the electronegativity differences are large enough, a ionic bond is formed where the most electronegative atom attracts both electrons. WebThe RDKit can generate conformations for molecules using two different methods. The original method used distance geometry. [1] The algorithm followed is: The molecule’s …
