The electron configuration for aluminum (Al) is shown below:

1s22s22p63s23p1

Which diagram shows the correct distribution of electrons in the electron shells of an aluminum atom?

A small orange dot is surrounded by 5 concentric circles. The inner ring has green dots at the north and south positions. The second ring has green dots at east and west. The third ring has six dots, at the north, northeast, southeast, south, southwest, and northwest. The fourth ring has dots at the north and south, and the outer ring has one dot at the west position.

A small orange dot is surrounded by two concentric circles. The inner circle has 6 green dots spaced approximately evenly across the circle. The outer circle has 7 dots, also approximately evenly spaced; none are aligned with dots in the inner circle.

An orange dot has 3 concentric circles surrounding it. The innermost circle has green dots at the north and south positions. The center circle has 8 dots spaced unevenly. The outer circle has three dots, spaced so that two are closer to each other than either is to the third.

An orange dot is surrounded by a concentric circle. 13 closely spaced green dots lie on that outer circle.
