In covalency
WebJul 30, 2024 · Key Takeaways. A covalent bond is formed between two atoms by sharing electrons. 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.
