- a. \( n = \text{principal quantum number}, \ n = 1, 2, 3, \ldots \)
- b. \( m_s = \text{spin quantum number}, \ m_s = +1/2 \ \text{or} \ -1/2 \)
- c. \( l = \text{subsidiary (or azimuthal) quantum number}, \ l = 1, 2, 3, \ldots, (n+1) \)
- d. \( m_l = \text{magnetic quantum number}, \ m_l = (-l), \ldots, 0, \ldots, (+l) \)
- e. The magnetic quantum number is related to the orientation of atomic orbitals in space.

**Question 18**

- a. Charged atoms (ions) must generate a magnetic field when they are in motion.
- b. Electrons of atoms in their ground states enter energetically equivalent sets of orbitals singly before they pair up in any orbital of the set.
- c. Two atoms of the same element must have the same number of protons.
- d. No two electrons in the same atom can have the same set of four quantum numbers.
- e. It is impossible to determine accurately both the position and momentum of an electron simultaneously.
