The size of an atomic nucleus is significantly smaller compared to the size of its electrons. The nucleus is the central core of an atom, consisting of protons and neutrons tightly bound together. The protons carry a positive charge, while the neutrons are electrically neutral. Electrons, on the other hand, are negatively charged particles that orbit around the nucleus.
The size of an atomic nucleus is typically on the order of femtometers (10^−15 meters). In comparison, the size of an atom is primarily determined by the electron cloud surrounding the nucleus. The electrons are much smaller than the nucleus, and their exact size is often considered negligible in relation to the overall size of the atom. The electron cloud extends over a much larger volume, and the average radius of an atom is typically on the order of angstroms (10^−10 meters) or picometers (10^−12 meters).
To put it in perspective, if we were to scale down an atom to the size of a football stadium, the nucleus would be approximately the size of a marble placed at the center, while the electrons would be like tiny specks or dust particles scattered throughout the stadium.
