Isotope analysis in archaeology is a scientific technique used to study the chemical signatures of materials, particularly human remains, animal bones, and artifacts, through the measurement of isotopic ratios. Isotopes are variants of elements that have the same number of protons but different numbers of neutrons, leading to differences in their atomic mass. The ratios of these isotopes can provide valuable information about past environments, diets, migration patterns, and social structures.

Tellurium (Te) has several isotopes, both stable and radioactive. The most common isotopes of tellurium are: 1. **Stable Isotopes:** - **Te-120**: The most abundant stable isotope, constituting about 33% of natural tellurium. - **Te-122**: Another stable isotope, making up about 52% of natural tellurium.

Thallium (Tl) has several isotopes, which are variants of the element with the same number of protons but different numbers of neutrons. Naturally occurring thallium has two stable isotopes: 1. **Thallium-203 (Tl-203)**: - Number of protons: 81 - Number of neutrons: 122 - Natural abundance: About 29.5%.
