Consider the orbitals shown below. A short line has an arrow pointing up from it and a second arrow pointing down to it. Beneath the line is the label 3 s. Beside it are three short lines. The first two of the lines have arrows pointing up from them. The centerline has the label 3 p under it. Which of these diagrams correctly shows the electron configuration for the atom with one more electron than the one shown above? A short line has both up and downward pointing arrows above it, and the label 3 s below it. Beside it are three more short lines; the first has an up and a down arrow, the second has an up arrow only, and the third has no arrows. The centerline of the three is labeled 3 p. A short line has an up and a down arrow above it, and the label 3 s below it. Beside it are three short lines. All three have up arrows. The centerline is labeled 3 p. A short line has an up and a down arrow above it, and the label 3 s below it. Beside it are three short lines. The first two have up arrows, and the third a down arrow. The centerline is labeled 3 p. A horizontal line with one up and one down arrow, labeled 3 s, and a group of three horizontal lines labeled 3 p. The first line has 2 up arrows, the second 1 up arrow, and the third is blank.
