Rutherford scattering - Study guides, Class notes & Summaries

LRA 211 Final Review Study Guide (223/2024) Graded A+ The earliest atomic theory based on an arrangement similar to the solar system is attributed to Rutherford. The three fundamental particles of the atom are the neutron, electron, and proton. The atomic nucleus contains protons and neutrons. The component of the nucleus that has a positive charge and mass is the proton. The electron shell closest to the nucleus is lettered "K". Which of the following is not part of the electromagnetic sp...

Nuclear Physics LATEST EDITION 2024/25 GUARANTEED GRADE A+ Properties of α radiation 2 Alpha particles can only be emitted by nuclei with an atomic number greater than 82. Typically, alpha particles cannot penetrate through a sheet of paper or a few mm of air. Rutherford Scattering In the early 20th century Ernest Rutherford conducted an experiment which completely changed our model of the atom. The experiment Rutherford conducted an experiment where he fired alpha particles at a very th...

What is an atom? - Ans .Smallest part of an element that can exist ▪ What is an element? - Ans .A substance made up of one type of atom ▪ How are elements represented? - Ans .Using symbols, in the periodic table ▪ Approximately how many elements are there? - Ans .100 ▪ What is a compound? - Ans .A substance made up of two or more elements chemically combined in fixed proportions ▪ How are the elements in a compound separated? - Ans .By chemical reaction ▪ How are chemical rea...

Atom definition The smallest component of an element Compound Two or more elements, chemically joined in fixed proportions. They can only be separated by chemical means. Mixture Two or more elements/compounds which are not chemically combined. Ways to separate mixtures - Filtration - Evaporation - Crystallisation - Simple distillation - Fractional distillation - Paper chromatography The plum and pudding model Before electrons were discovered, people thought that atoms were indivi...
