Questions & Step-by-Step Solutions

What is the principal quantum number of an electron in the 3p orbital?
Correct Answer: 3
  • Step 1: Understand what the principal quantum number (n) is. It tells us the energy level of an electron in an atom.
  • Step 2: Look at the name of the orbital given, which is '3p'.
  • Step 3: Identify the number in front of the letter 'p'. This number is the principal quantum number (n).
  • Step 4: In '3p', the number is 3, so n = 3.
