Chemistry A - Coggle Diagram

- - - - Atoms are in everything
      - Atoms of the same element are identical
      - Atoms can combine with other atoms in simple ratios
      - Chemical reactions rearrange the atoms but don’t change their identity
  - - - Always a whole number
      - Number of protons
      - Periodic tables built on this number
  - - - Groups of families
    - - Periods
- - - - Chemical formula
      - Show elements and ratio
      - Single molecule is a molecular formula
      - Empirical formula - lowest whole-number ratio
      - Ionic compound - large complex with many pieces together
    - - One type of element with a charge
    - - Cation - positive ion - generally metals
        
        listed 1st in formulas
      - Anion - negative ion - generally non metals
        
        2nd in formulas
- - - - Anything that has mass and takes up space
        
        Microscopic organisms
        
        small particles that make up matter
        
        Macroscopic organisms
        
        can be seen and touched
- - - - Anything that has mass and takes up space
    - - Amount of matter in an object
    - - Space that's occupied by an object
    - - Matter that's uniform and definite composition
    - - Characteristic of a substance that can be observed or measured without changing the substance
      - Color, hardness, malleability (molded into sheets) solubility, electrical conductivity, magnetism, density, melting point, boiling point
  - - - Something that stays mixed together, you can't see through
    - - Somethin that does't stay mixed together, like most food, soil
    - - Filtration
      - Distillation
      - Crystallization
      - Chromatography
