FAQs on Size of the Nucleus Video Lecture - Physics Class 12 - NEET

1. What is the size of the nucleus?
Ans. The size of the nucleus is extremely small compared to the overall size of an atom. It has a diameter of approximately 1 to 10 femtometers (1 femtometer = 10^-15 meters).
2. How does the size of the nucleus compare to the size of the atom?
Ans. The size of the nucleus is much smaller than the overall size of an atom. The nucleus contains most of the atom's mass, while the electron cloud surrounding the nucleus accounts for the majority of the atom's volume.
3. What determines the size of the nucleus?
Ans. The size of the nucleus is determined by the number of protons and neutrons it contains. As the number of protons and neutrons increases, the size of the nucleus also increases.
4. Can the size of the nucleus vary within an atom?
Ans. No, the size of the nucleus remains constant within an atom. However, different atoms can have nuclei of different sizes depending on the number of protons and neutrons they possess.
5. How is the size of the nucleus measured?
Ans. The size of the nucleus is measured using various experimental techniques, such as scattering experiments and electron microscopy. These techniques allow scientists to indirectly determine the size of the nucleus based on the interactions and behavior of particles and waves with the nucleus.
