WebThe valence electrons are the electrons in the outermost electron shell of an atom. That is why elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table. Generally, elements in Groups 1, 2, and 13 to 17 tend to react to form a closed shell, corresponding to the electron configuration s2p6. WebHowever, one atom only has two electrons, so it could never have more than 2 valence electrons. As noted above, helium is the only exception for the main group elements. Potassium (K) is located in Group IA (Group 1), so it has 1 valence electron. Aluminum (Al) is located in Group IIIA (Group 13), so it has 3 valence electrons. ️ Exercise 10.6. 1
