8
Chemical Reactions
  • Conservation of Mass – Mass cannot be created or destroyed in a chemical reaction
  • Review Chemical Reactions Vision Learning
  • Review Chemistry Concepts
9
Physical and Chemical Properties
  • Every substance (element/compound) has a unique set of properties that allow scientists to tell it apart from other substances.
  • Physical Property – A substance’s color, odor, density, melting point and boiling point, ductility, and conductivity
10
Physical and Chemical Properties
  • Chemical Property – Ability of a substance to react with other substances
  • Review Physical and Chemical Changes
11
States of Matter
  • Solid – Have  a definite volume and shape; particles vibrate in place
  • Liquid – Have volume but no definite shape; particles flow past each other
  • Gas – No definite volume and no definite shape; particles move independently in high speeds and in all directions
  • Plasma – Occurs in extremely high temperatures Examples: stars, lightning, neon lights
  • Review States of Matter
12
Periodic Table of Elements
  • Table of elements arranged by their atomic number.
  • An element’s position on the table will show many of its general properties
  • Groups – Members of the same group have similar chemical and physical properties
  • Periods – Change gradually from left to right
13
Compounds, Mixtures, Solutions
  • Compounds – made of 2 or more elements chemically combined
  • Mixture – 2 or more substances mixed together without chemically combining; can be separated without a chemical reaction
  • Solution – a mixture in which one substance is dissolved uniformly in another substance
  • Review Solutions, Mixtures, Compounds
14
Elements
  • Metals – Hard, shiny elements appearing on the left side of the Periodic Table; good conductors of heat and electricity; Examples: Fe, Al, Na
  • Metalloids – Appear along the bolded line on the Periodic Table; conduct electricity under some conditions; Examples: B, Si
  • Nonmetals – Appear to the right of the Periodic Table;  poor conductors of electricity; many are gases or brittle solids; Examples: C, O, S
15
Elements
  • Noble Gas – Appear to the far right of the Periodic Table; do not combine with other substances; Examples: Ar, Ne
  • Review Periodic Table
