British physicist Ernest Rutherford proposed a nuclear model of the atom, in which a nucleus exists, in 1911. He also discovered activity in this part, namely the movement of protons and electrons within the central part of the atom. He further postulated that the number of protons in an atom equals that of the …
WebbLived 1779 – 1848. Jacob Berzelius was one of the founders of modern chemistry. He was the first person to measure accurate atomic weights for the elements, which helped to confirm Dalton's Atomic Theory and was the basis of Mendeleev's periodic table. He discovered three chemical elements: cerium, thorium, and selenium, and devised the … Webb24 feb. 2024 · If one atom decays, the Geiger counter observes that decay and responds to it automatically. The GC "discharges". The discharge hits a relay, which triggers a hammer, which breaks the vial. Up until that time, the cat is alive. After it, the cat dies. If no atom decays within the allotted hour, the cat lives. The cat is never both alive and dead.
