Questions & Step-by-Step Solutions

What is the value of the principal quantum number (n) for an electron in the ground state of a hydrogen atom?
  • Step 1: Understand what the principal quantum number (n) represents. It indicates the energy level of an electron in an atom.
  • Step 2: Identify what the ground state of an atom means. The ground state is the lowest energy state of an electron.
  • Step 3: Know that for hydrogen, the lowest energy level (ground state) is the first energy level.
  • Step 4: Assign the value of the principal quantum number (n) for the first energy level, which is n=1.
