1. ACIDS AND ALKALIES

   • ACIDS
     • A SUBSTANCE THAT REACTS WITH AN ALKALI TO FORM A NEUTRAL SOLUTION
     • NOT ALL ACIDS CAN BURN YOUR SKIN
     • ACIDS ARE NOT ONLY FOUND IN LABORATORIES.
   • NEUTRALS
     • A SOLUTION THAT IS NOT ACIDIC OR ALKALINE NEUTRAL SOLUTION HAVE A pH OF SEVEN
     • WHAT IS NEUTRALISATION? IT IS A CHEMICAL REACTION BETWEEN AN ACIDS AND AN ALKALI
       • THE COLOUR OF NEUTRAL SUBSTANCE IN AN UNIVERSAL INDICTOR IS GREEN
       • IF THE ACID AND ALKALI IS MIXED AND BOILED REALLY EVENLY THEN IT IS THEORETICALLY EDIBLE SALT
   • ALKALINES
     • ALKALI IS A SUBSTANCE THAT REACTS TO AN ACID TO FORM A NEUTRAL SOLUTION
     • ALKALIES ARE NOT SAFE TO TOUCH WITHOUT GLOVES
     • ALKALIES ARE NOT ONLY FOUND IN LABORATORIES
   • ACID + ALKALI --> SALT + WATER

2. ATOMS ELEMENTS AND COMPOUNDS

   • ATOMS
     • ALL THINGS ARE MADE OF ATOMS
     • ATOMS ARE SO SMALL, YOU CANNOT SEE WITH THE NAKED EYE OR A NORMAL MICROSCOPE AND NEEDS TO USE A SPECIAL MICROSCOPE
     • PROTON
       • RELATIVE MASS 1
       • CHARGE +1
     • NEUTRON
       • RELATIVE MASS 1
       • CHARGE 0
     • ELECTRON
       • RELATIVE MASS ALMOST 0
       • CHARGE -1
   • ELEMENTS
     • THE SAME ATOMS JOINED TOGETHER
     • MOLECULES
