PPT-Counting Elements and Atoms

Presented by Kesler Science How are chemical formulas used to identify substances How do chemical formulas determine the number of atoms of each element using subscripts coefficients and parenthesis.

Elements are divided into metals and non-metals. Examples of non-metal elements include carbon, oxygen, hydrogen, and nitrogen. Counting Chapter 6 With Question/Answer Animations The Basics of Counting Section 6 . 1 Basic Counting Principles: The Product Rule The Product Rule : A procedure can be broken down into a sequence of two tasks. There are Rock, wood, air, metal, water, and animals are all matter. Matter. Elements. The various forms of matter are composed of one or more chemical elements. . An . element. is a pure substance that cannot be broken down into other substances by chemical means. . For Example: If you have a piece of gold and cut it into smaller and . smaller pieces, . you would eventually reach a point where you couldn’t cut the gold up any smaller. That smallest piece would be an atom of gold.. They can be joined together by . chemical bonds. From last lesson:. Atoms can have different numbers of protons, neutrons and electrons.. There are 118 different types of atoms.. They can be found on the periodic table of elements..
