Questions & Step-by-Step Solutions

Which quantum number can have a value of 0?
Correct Answer: Azimuthal quantum number (l)
  • 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), azimuthal (l), magnetic (m), and spin (s).
  • Step 3: Focus on the azimuthal quantum number (l). This number describes the shape of the orbital where an electron is likely to be found.
  • Step 4: Know the possible values for the azimuthal quantum number (l). It can be 0, 1, 2, etc.
  • Step 5: Recognize that when l = 0, it corresponds to an s orbital, which is spherical in shape.
  • Step 6: Conclude that the azimuthal quantum number (l) is the quantum number that can have a value of 0.
