WebAnswer: is If by 21 c your mean 21 - carbon atoms then Number of neutrons for one carbon atom is 6. .. Number of neutrons for 21 carbon atoms = 21 x6 . = 126.. 11) If by 2 1 6 you mean isotope ac, then the question is wrong as 21c does not exists. But, in a hypothetical situation, if a c exists, it implies the mass number ; A = 21. WebJul 7, 2024 · An atom has a nucleus (or core) containing protons and neutrons, which is surrounded by electrons. Protons carry a positive electrical charge, and electrons carry a negative electrical charge. Neutrons do not have an electrical charge. Enormous energy is present in the bonds that hold the nucleus together. This nuclear energy can be released ...
