In this lecture you will learn about Atomic Theory and Measurement. Our instructor will first guide you through Dalton's Atomic Theory and its Law of Multiple Proportions before covering the Current Atomic Theory with its Components (Electrons, Protons, Neutrons), Isotopes, and Complex Molecules. Then you will learn the Fundamental Definition of an Element with its Nuclear Charge (z), Atomic Number, and Isotopes. Finally, you will understand Atomic Masses, Measurement in various SI Units (Meter, Kilogram, Second, Kelvin, Liter), and Measuring Quantities such as Height and Volume.
Atomic Theory: statements which shaped atomic theory for years;
atoms cannot be cut, atoms of one element are identical, compounds
are made from small numbers of atoms
of Multiple Proportions: definition
Atomic Theory: atoms have components (protons, electrons, neutrons);
atoms of same element may have different masses (isotopes)
charge Z is an integer and identifies an element
Masses are in amu, isotopes have different number of neutrons
the basic SI units and multipliers
