Web27 jul. 2024 · full ground state electron configuration: 1s^2 2s^2 2p^6 3s^2 3p^5 abbreviated: "[Ne]" 3s^2 3p^5 Chlorine has an atomic number of 17, which means it has 17 protons and therefore 17 electrons in its atomic form. We'll need to know how many sublevel is present in each energy level, and in turn, how many electrons each sublevel … WebElectrons that are not in the valence level are not shown in the Lewis symbol. The reason for this is that the chemical reactivity of an atom of the element is solely determined by the number of its valence electrons, and not its inner electrons.Lewis symbols for atoms are combined to write Lewis structures for compounds or molecules with bonds between atoms.
