How does charge density vary in P-orbitals?

• A. It is constant throughout
• B. It decreases with distance from the nucleus
• C. It increases with distance from the nucleus
• D. It is highest at the nucleus

Answer: (C)

In P-orbitals, charge density refers to the probability of finding electrons at various distances from the nucleus. P-orbitals have a distinct shape that is dumbbell-like, extending outwards from the nucleus. The charge density does not remain constant nor does it peak at the nucleus. Instead, it decreases as you move away from the nucleus. As you get farther from the nucleus, the regions where the electron is likely to be found (the lobes of the P-orbital) become less densely populated with charge. This is because the probability of finding the electron decreases with distance due to the wave nature of electrons and the shape of the orbital. The highest probability of finding an electron in a P-orbital occurs further away from the nucleus, in line with the lobes of the orbital. Therefore, the understanding of charge density in P-orbitals hinges on the shape and spatial distribution of the orbitals, which show that while electrons may be found farther from the nucleus, the density of charge diminishes closer to that region, supporting the idea that charge density decreases with distance from the nucleus.
