Which statement correctly describes an atom of the element helium? A. An atom of helium has a full outer energy level and is the
refore unusually reactive. B. An atom of helium most similarly behaves like an atom of hydrogen since it is in the same period. C. An atom of helium has its valence electrons in its first energy level. D. An atom of helium has eight electrons in its outer energy
The correct description for an atom of helium would be option C. An atom of helium has its valence electrons in its first energy level, it wouldn't and can't satisfy the Octet rule as it only has 2 electrons, but with 2, it has a full shell, as the first energy level can hold only 2 electrons.
