WebJul 31, 2024 · The most frequently used tracers are stable isotopes and tritium. Stable isotopes of oxygen (δ 18 O) and hydrogen (δ 2 H) are mainly used as indicators of the recharge condition. Tritium (3 H) is used to estimate an approximate mean groundwater age. This paper presents the results of an analysis of stable isotope data and tritium … WebAug 2, 2024 · mass number = (number of protons) + (number of neutrons) mass number = 3 + 4 = 7 Notice that because the lithium atom always has 3 protons, the atomic number for lithium is always 3. The mass number, however, is 6 in the isotope with 3 neutrons, and 7 in the isotope with 4 neutrons. In nature, only certain isotopes exist. newcastle 95/96
