Tömegszámú
Tömegszámú is a Hungarian term that translates to "mass number" in English, a fundamental concept in nuclear physics and chemistry. It represents the total number of protons and neutrons within an atomic nucleus. This value is crucial for understanding isotopes, which are atoms of the same element (meaning they have the same number of protons) but differ in their number of neutrons, and therefore, in their mass number.
The mass number is denoted by the symbol 'A'. It is determined by summing the atomic number
The mass number is distinct from atomic mass, which is the actual mass of an atom, typically
