Document Summary
Chemistry 1127q- lecture 4-chapter 1 completion & chapter 2 introduced. Topics covered: 1. 5 measurement uncertainty, accuracy, and precision continued, 2. 1 early ideas in atomic theory, 2. 2 evolution of atomic theory. Accuracy and precision: accuracy tells us how close a measurement is to the true value, precision tells us how close a series of replicate measurements are to one another. 2. 1 early ideas in atomic theory: an atom is defined as. : the smallest quantity of matter that still retains the properties of matter: an element is define as. : a substance consisting of all one type of atom. 5 rules that make up dalton"s theory: matter is composed of exceedingly small particles called atoms. This law states samples of a pure compound contain the same elements in the same proportion by mass. ***this law differs from dalton"s law of multiple proportions ***
