In which of the following orbitals would an electron have the highest energy?

In which of the following orbitals would an electron have the highest energy?

Step 1: Understand what an orbital is. An orbital is a region in an atom where there is a high probability of finding an electron.
Step 2: Learn about the principal quantum number (n). This number indicates the energy level of the electron and how far it is from the nucleus.
Step 3: Identify the principal quantum numbers for the given orbitals. For example, the 3s orbital has n=3.
Step 4: Compare the principal quantum numbers of the orbitals. The higher the number, the higher the energy.
Step 5: Conclude that since the 3s orbital has the highest principal quantum number (n=3), it has the highest energy among the options.
