How are these two pictures related How to fold your paper Hold the paper lengthwise and fold the edges into the center Flip the paper over and write Agree or Disagree at the top Number 15 down the paper. Suppose you went to the video store and all the videos were mixed together. How could you tell the comedies from the action movies? If the videos were not arranged in a pattern, you wouldn’t know what kind of movie you had chosen.. By Ms. Renfro. The two categories of matter. Pure Substances.

Pure Substances. A sample of matter that has definite chemical and physical properties.. Elements. Atoms. Compounds. Molecules. Elements. pure substance that cannot be separated into simpler substance by physical or chemical means. . What is an element?. A element is a pure substance made of one type of atom. Elements are divided into metals and non-metals. Examples of non-metal elements include carbon, oxygen, hydrogen, and nitrogen. Elements with similar properties occurred in regular intervals (periodic). Henry Mosely 1914- rearranged the table based on atomic number once protons were discovered. Atomic number- number of protons in one atom of the element. Chapter 1 Matter on the Atomic Scale Chemistry The science of matter and the transformations it can undergo. Consider the anticancer drug Taxol ® . Why should you study it? It helps us understand our surroundings and the way we function. 2. . How many different types of atoms is helium made up of?. 3. Draw the Bohr model for helium (there are two neutrons in helium).. Today’s Objectives. SWBAT explain that a ‘chemical formula’ describes the combination of two or more elements.. Atoms are the basic units of all matter.. Protons . (+) . Neutrons . (0. ). Electrons (-). Atoms are composed of 3 sub-atomic particles:. . An atom is the smallest particle of an element.. Elements. CONTENTS. CHEMICAL REACTION. CHARACTERISTICS OF CHEMICAL REACTION. TYPES OF CHEMICAL EQUATION. BALANCING OF CHEMICAL EQUATION. HOW TO MAKE EQUATION MORE INFORMATIVE. 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.. history. A 100,000-year-old ochre-processing workshop was found at . Blombos. Cave in South Africa. It indicates that early humans had an elementary knowledge of chemistry. Paintings drawn by early humans consisting of early humans mixing animal blood with other liquids found on cave walls also indicate a small knowledge of chemistry.
