Periodic Table

• Physical properties are the basic features of a material that affects how it behaves in different situations. e.g. - Metal is a good conductor of heat
• chemical properties describe how a subject looks and behaves.
• The chemical formula for a substance shows how many atoms of each element are present in a molecule, or the proportion of atoms of each element.
• The melting point is usually defined as the point at which materials changes from a solid to a liquid. 
• The boiling point  is the temperature at which the substance transitions from a liquid to the gaseous phase.
•  The freezing point is the exact temperature at which a liquid becomes a solid. 
• Elements in the same group in the periodic table share chemical properties and will most of the time have similar outcomes - Word equations include: metal + water = metal hydroxide + water and metal + oxygen = metal oxide
