WebAug 9, 2024 · The valence electrons participate in chemical reactions. The main group elements are the A groups, or groups 1,2,13-18. The core electrons are in the inner shells and do not participate in chemical reactions. You can determine the number of valence electrons in the atoms of the main group elements by the group number of the element. WebThe biggest jump (change) is between IE5 and IE6 so I would guess that from IE6 & up we are removing core electrons. This means that we most likely have 5 valence electrons, meaning we would be in the 15th group on the periodic table, meaning we would guess Phosphorous (P).
