Questions & Step-by-Step Solutions

What is the value of the principal quantum number for an electron in the ground state of a hydrogen atom?
  • Step 1: Understand what the principal quantum number (n) is. It indicates the energy level of an electron in an atom.
  • Step 2: Know that the ground state of an atom is its lowest energy state.
  • Step 3: For hydrogen, the lowest energy state (ground state) corresponds to n=1.
  • Step 4: Therefore, the value of the principal quantum number for an electron in the ground state of a hydrogen atom is n=1.
