For each of the following atoms or ions, state the total number of electrons, the number of valence electrons, and the number of core electrons. (a) Rn (b) Sr+ (c) Se2 (d) Sb2. WebThe Octet Rule and Its Exceptions. The octet rule states that atoms below atomic number 20 tend to combine so that they each have eight electrons in their valence shells, which gives them the same electronic configuration as a noble gas. The rule is applicable to the main- group elements, especially carbon, nitrogen, oxygen, and the halogens ... WebThe total number of valence electrons a whole compound would have. (Meaning how many more electrons does each atom have than the noble gas before it, then add up that number of electrons for all the atoms to get total valence electrons.)
