mAcroscopic- observation and manipulations generally take place in this world of chemistry. Submicroscopic or particulate level – level of individual particles that make up all matter. Sir Joseph John Thomson – proved the existence of the electron. Ernest Rutherford – deserves most credit for the discovery of the proton. James Chadwick – discovered the existence of neutrons. Molecular formula – describes the composition of molecules. Condensed formula – indicates how certain atoms are grouped together. Empirical formula – simplest whole number atom ratio. Hydrated compounds – compounds in which molecules of water are associated with the ions of the

Unformatted text preview: compound. Exchange reactions the ions of the reactants change partners. Precipitation reaction ions combine in solution to form an insoluble reaction product. Acid-Base reaction water is a product and the cation of the base and the anion of the acid form a salt. Gas Forming reaction most commonly CO2 is given off as a product. Redox reactions The reducing agent is itself oxidized , and the oxidizing agent is reduced . Oxidation is the opposite of reduction. The r emoval of oxygen is r eduction and the addition of oxygen is oxidation. Photoelectric effect ejection of electrons when light strikes the surface of a metal....
