Which of the following quantum numbers describes the shape of an orbital? (2020) 2020
Step 1: Understand what quantum numbers are. They are numbers that describe the properties of atomic orbitals and the electrons in those orbitals.
Step 2: Identify the different types of quantum numbers. There are four types: principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m_l), and spin quantum number (m_s).
Step 3: Focus on the azimuthal quantum number (l). This number specifically indicates the shape of the orbital.
Step 4: Remember that different values of l correspond to different shapes: l = 0 is spherical (s), l = 1 is dumbbell-shaped (p), l = 2 is double dumbbell (d), and l = 3 is more complex (f).
Step 5: Conclude that the azimuthal quantum number (l) is the correct answer to the question about which quantum number describes the shape of an orbital.
