- MCAT Question of the Day
What is the azimuthal quantum number (l) for the orbital to which a fluorine atom gains an electron to form an F- ion?
Click for Explanation
The orbital shapes commonly referred to as s, p, d, and f, correspond to azimuthal quantum numbers of 0, 1, 2, and 3, respectively.
The electron configuration for elemental fluorine is 1s22s22p5. When fluorine gains an electron to become F–, the electron adds to the p orbital. P orbitals are dumbbell shaped with one angular node and correspond to an azimuthal quantum number of 1, making B the correct answer.
