Rutherford had been puzzled been puzzled by one observation from his experiments with nuclei. After the collisions, the nuclei seemed to be heavier. Were did this extra mass come from? James Chadwick, a student of Rutherford's, answered this question. The alpha particles themselves were not heavier. The atoms that had been bombarded had given off new particles. Chadwick experimented with these new particles and found that, unlike electron's, the paths of these particles were notaffected by an electric field. To explain his observations, he said that these particles came from the nucleus and had no charge. Chadwick called these particles uncharged particles neutrons(NEW trahnz). His proton-neutron model of the atomic nucleus is still excepted today.

What experiments did Antoine Lavoisier perform?

Lavoisier conducted a number of experiments that were based on the assumption that matter can neither be created nor destroyed and validated it through the experiments. This led to the formulation of the Law of Conservation of Mass (or Matter).

Marie Paulze Lavoisier was instrumental in bringing his experiments to publication as she translated documents and illustrated his scientific texts with incredible competence and efficiency.

What are the the contributions of Antoine Laurent Lavoisier to field of chemistry?

Antonine Laurent Lavoisier's contributions: Research on gases, water, and combustion Antoine Lavoisier's famous phlogiston experiment. The work of Lavoisier was translated in Japan in the 1840s. Pioneer of stoichiometry Lavoisier's researches included some of the first truly quantitative chemical experiments. Analytical chemistry and chemical nomenclature Lavoisier investigated the composition of water and air, which at the time were considered elements. Legacy Constant pressure calorimeter. Lavoisier's fundamental contributions to chemistry were a result of a conscious effort to fit all experiments into the framework of a single theory.

Why could the neutron not be discovered in same experiments as the electron and proton?

Early experiments were based off attraction. The neutron had no charge to attract or repel or to be attracted or repelled. so these experiments could not figure out that there was a neutral particle in the nucleus.


What distinguishes Lavoisier's experiments from his predecessor's?

His experiments were based on quantitative data, not qualitative. Also, he was extremely accurate which was not the case for his predecessors. This allowed him to then develop the Law of Conservation of Mass.


Did Newton discover that fire needs oxygen to burn?

No, the credit for this one goes to Antoine Lavoisier, a French chemist. Lavoisier was in contact by mail with an English husband and wife team called Cavanaugh who were doing similar experiments. Lavoisier was a tax collector and was executed via a guillotine in the French revolution.
