Questions & Step-by-Step Solutions

If the principal quantum number n = 4, what are the possible values of the azimuthal quantum number l?
  • Step 1: Understand what the principal quantum number (n) represents. It indicates the main energy level of an electron in an atom.
  • Step 2: Identify the given value of n, which is 4 in this case.
  • Step 3: Know that the azimuthal quantum number (l) can take values starting from 0 up to n-1.
  • Step 4: Calculate the maximum value for l by subtracting 1 from n: 4 - 1 = 3.
  • Step 5: List all possible values for l, which are 0, 1, 2, and 3.
  • Principal Quantum Number (n) – Indicates the main energy level of an electron in an atom.
  • Azimuthal Quantum Number (l) – Determines the shape of the electron's orbital and can take values from 0 to n-1.
