Answer 1

The element that does not have the same number of electrons in its outermost shell as the other elements in its group is helium (He). Helium is in Group 18 (the noble gases) and has 2 electrons in its outermost shell, while the other elements in that group (like neon, argon, etc.) have 8 electrons in their outermost shell according to the octet rule.
