Beginning in 1945 with the. Answer: Well, first of all, the "standard" notation is ZXA, not AZX. In this case, since isotopes are known be atoms of the same element with equal atomic number but different mass number, we can consider the case of carbon which has two natural occurring ones, carbon-12 and carbon-13 whereas carbon-12 has the greatest abundance. Both exist in equal amounts. The hydrogen-1 may also be referred to as protium, hydrogen-2 as deuterium, and hydrogen-3 as tritium.) "Z" is the number of protons, X is the chemical symbol, and "A" is the number of nucleons. However, isotope notation may take two forms: 1. 6,6,6 7. Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. Ernest Rutherford, 1st Baron Rutherford of Nelson, OM, FRS, HonFRSE (30 August 1871 - 19 October 1937) was a New Zealand physicist who came to be known as the father of nuclear physics. Isotope notation, also known as nuclear notation, is important because it allows us to use a visual symbol to easily determine an isotope's mass number, atomic number, and to determine the number of neutrons and protons in the nucleus without having to use a lot of words.
