Do you need to know how electromagnetic waves can be produced by accelerated charge and other important aspects of high school chemistry? This free online course provides you with an in-depth understanding of the rules of identifying significant figures. It is important to understand the process of data collection by making, adding, subtracting and dividing the measurements. Before working with scientific notations, it is essential to know how the decimal point can be moved directly after the first significant figure. This course takes you through the metric system, dimensional analysis and the different physical states of matter. Do you know why substances are separated and why the number of atoms in a compound is based on the chemical formula? This course will teach you the crucial procedures you need to know.

If you want to understand the concept of heterogeneous and homogeneous mixtures, including the types of pure substances, then sign up today. Once you have finished the modules, you should be able to explain the properties of metals, non-metals, metalloids and various types of energy associated with matter. You will also have a better understanding of nuclei, electrons, neutrons and protons. Do you know it is possible to determine the number of particles an atom contains? The material examines the Dalton and Thomson models of the atom and illustrates the production of positive rays and the gold foil experiment. It also clarifies the Rutherford model of the atom and number of neutrons in the nucleus.

Furthermore, you will learn about isotopes and the atomic mass of an element. Break down the concept of molecular mass, the Bohr model of the atom, and the electromagnetic spectrum. Do you know the working principle for photoelectron spectroscopy? This course helps you understand schematics and representation of mass spectroscopy, and explains in detail the characteristics of Hertz's experiment. Study the applications of electromagnetic waves, wavelength and frequency. You will learn about the technique that determines the absorption of UV and visible light in solutions in transmission mode. This free online course will prepare you for the AP chemistry exam and aid all high school students to achieve better results in general chemistry.
