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 hydrogen (H).

Hydrogen has one electron in its outermost shell, while the other elements listed (bromine, boron, and helium) have more than one electron in their outermost shells. Helium has two electrons, boron has three, and bromine has seven.
