It is convenient to describe the composition of an atom in terms of the number of protons and neutrons in its nucleus (Figure 1 ). The term atomic number , conventionally denoted by the symbol Z , indicates number of protons present in the nucleus of an atom, which is also equal to ...
As target nuclei, we take $^{6}$He and neutron-rich Ne isotopes in addition to stable nuclei of mass number $A=4$--$208$ in order to clarify mass-number and isotope dependence of $U$. The local potentials reproduce the experimental data systematically and have geometries similar to the...

An atom has an atomic number of 12 and a mass number of 25. how many neutrons does the atom have? How can you find atomic number from mass number? Which of among the atomic number, mass number and isotopes distinguishes one element from one another? Explain your answer. ...
- Number of neutrons = Mass number - Atomic number = 12 - 6 = 6- Thus, Carbon (C) has 6 protons, 6 neutrons, and a mass number of 12. --- (iii) Isotopes:Isotopes are atoms of the same element that have the same atomic number (same number of protons) but different mass ...

Thus, its mass number is 12. While the number of protons remains the same in all atoms of an element, the number of neutrons can vary. Thus, atoms of the same element can have different mass numbers, and these are called isotopes. The weight of an electron is almost negligible. Thus,...
