The diameter of a nucleus is:
Correct answer: A. 10-12 m
- A. 10-12 m
- B. 10-20 m
- C. 10-10 m
- D. 10-15 m
Explanation
a) 10^-12 m:This option suggests that the diameter of a nucleus is 10^-12 meters. This is a valid approximation for the typical size of a nucleus. Nuclei are incredibly small, and their diameters range from about 10^-14 meters to 10^-15 meters, depending on the element.

About Composition of Atomic Nuclei
Atomic nuclei contain positively charged protons and electrically neutral neutrons, collectively called nucleons. Questions use atomic number, mass number and nuclear notation to identify isotopes, isobars and isotones, and may connect nuclear composition with nuclear charge, mass defect, binding energy and the stability of the nucleus.
