Web8 dec. 2024 · seven valence electrons The Group 7A elements have seven valence electrons in their highest-energy orbitals (ns2np5). This is one electron away from having a full octet of eight electrons, so these elements tend to form anions having -1 charges, known as halides: fluoride, F-; chloride, Cl-, bromide, Br-, and iodide, I-. WebWell that means that there can be up to six electrons in each energy level for the p orbitals. so then we would say 2p4 2 = the energy level we are on p = the type of orbital 4 = the number of electrons needed to complete oxygen's number of 8 So oxygen's electron configuration is: 1s2 2s2 2p4
