Q: Which quantum number is not allowed to be negative?
Solution: The principal quantum number (n) cannot be negative; it must be a positive integer.
Steps: 5
Step 1: Understand what quantum numbers are. They are numbers that describe the properties of electrons in an atom.
Step 2: Learn about the different types of quantum numbers. There are four main types: principal (n), angular momentum (l), magnetic (m), and spin (s).
Step 3: Focus on the principal quantum number (n). This number indicates the energy level of an electron.
Step 4: Remember that the principal quantum number (n) must always be a positive integer (1, 2, 3, ...).
Step 5: Realize that the other quantum numbers can have negative values, but the principal quantum number cannot.
