Detailed explanation-1: -Thus, If A is the mass number and Z is the atomic number of an element, then the number of neutrons is A-Z Mass number (A)-Atomic number (Z).
Detailed explanation-2: -Here, X is the particular element, A is the element’s mass number and Z is the atomic number of the element. The Z (atomic number) value of an element gives the count of protons in the element.
Detailed explanation-3: -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 the number of electrons in an uncharged atom. The number of neutrons is represented by the neutron number (N).
Detailed explanation-4: -An element is represented by ZXA, where Z is atomic number which is also equal to number of proton, A is mass number and X is symbol of the element. Mass number (A) = Number of protons (Z) + Number of neutrons.
