The electron configuration for Helium (He) is shown below. 1s2 Which diagram shows the correct distribution of electrons in the electron shells of a helium atom? A gray circle labeled 1 P 0 N is surrounded by a concentric circle with one gray dot at the north position. A gray circle is labeled 5 P 6 N. It is surrounded by two concentric circles. The inner circle has gray dots at the north and south positions. The outer circle has three evenly spaced dots; none of these align with the dots in the inner circle. A gray circle is labeled 2 P 2 N. A concentric circle surrounding it has two gray dots, at the north and south positions. A gray circle is labeled 6 P 6 N is surrounded by two concentric circles. The inner circle has dots at the north and south positions; the outer circle has dots at the north, south, east, and west positions.
