The number of bonds an element forms in a covalent compound is determined by the number of electrons it needs to reach octet. Hydrogen is an exception to the octet rule. H forms only one bond because it needs only two electrons. WebJul 5, 2024 · Consider a simple system of a single electron and proton separated by a fix distance. The unit charge on an electron is 1.60 X 1019 C and the proton & electron are 100 pm apart (about the length of a typical covalent bond), the dipole moment is calculated as: μ = Qr = (1.60 × 10 − 19C)(1.00 × 10 − 10m) = 1.60 × 10 − 29C ⋅ m. is scare group of burds
