CHEMICAL INTERACTIONS INVESTIGATION 2: ELEMENTS

KEY CONCEPTS AN ELEMENT IS A BASIC SUBSTANCE THAT CANNOT BE BROKEN INTO SIMPLER SUBSTANCES DURING CHEMICAL INTERACTIONS. GOLD = Au THERE ARE 90 NATURALLY OCCURRING ELEMENTS ON EARTH. ELEMENTS COMBINE TO MAKE ALL THE SUBSTANCES ON EARTH EACH ELEMENT HAS A NAME AND REPRESENTED BY A 1 OR 2 LETTER SYMBOL

KEY CONCEPTS DIFFERENT LOCATIONS IN THE UNIVERSE HAVE DIFFERENT AMOUNTS OF ELEMENTS (EARTH HAS A LOT!) ELEMENTS COMBINE TO MAKE ALL THE SUBSTANCES ON EARTH ALL COMMON MATTER IS MADE OF ELEMENTS

KEY CONCEPTS THE PERIODIC TABLE OF THE ELEMENTS DISPLAYS ALL THE NATURALLY OCCURRING AND SYNTHESIZED ELEMENTS. EACH BOX HAS A DIFFERENT ELEMENT. ELEMENTS ARE THE BUILDING BLOCKS OF MATTER. EVERYTHING ON EARTH THAT HAS MASS & TAKES UP SPACE IS MADE OF COMBINATIONS OF ELEMENTS.
