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. WebAn atom's covalency tells us how many electrons the atom can donate in order to form covalent bonds. When drawing Lewis structures, each atom participating in a covalent chemical bond donates one...
