Stas was born on August 21, 1813 in Leuven, Belgium.
Stas studied for a medical career and took his doctor's degree, but soon turned to chemistry.
Stas worked at the École Polytechnique in Paris under the direction of Jean-Baptiste Dumas. Stas and Dumas established the atomic weight of carbon by weighing a sample of the pure material, burning it in pure oxygen, and then weighing the carbon dioxide produced. In 1840 he left Paris on his appointment to the chair of chemistry at the Ecole Royale Militaire in Brussels.
Stas's name is best known for his determination of the atomic weights of a number of the more important elements. His work in this field was marked by extreme care, and he adopted the most minute precautions to avoid error, with such success that the greatest variation between his numerous individual determinations for each element was represented by from 0-005 t° 0 01. Though he started with a predilection in favour of Prout's hypothesis he was later led by the results he obtained and by his failure to find any evidence of dissociation in the elements to regard it as a pure illusion and to look upon the unity of matter as merely an attractive speculation unsupported by proof. Nevertheless, a few years before his death, a propos of the close approximation to integers presented by a number of the atomic weights of the elements when hydrogen is taken as unity.
