Unfilled valence shell of electrons

WebJan 25, 2024 · Valence electrons or outer-shell electrons are indicative of an atom’s reactivity. The presence of eight electrons in the valence shell of an atom imparts stability to that particular atom. To attain stability, atoms transfer or share electrons within themselves in such a way that they can satisfy the octet rule and attain noble gas configuration. WebJun 22, 2024 · If you use the numbering system of labeling each group from left to right as 1-18, groups 1 and 2 have one valence electron and two valence electrons respectively. For groups 13-18, the number of valence electrons is the group number minus 10. Group 1/IA/1A: one valence electron Group 2/IIA/2A: two valence electrons
