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.
