• avogadros law - the volume of gas is directly proportional to the number of moles of the gas present at constant temperature and pressure
• atom - is the smallest particle of an element
• bioelements - the main bioelement that make up living things mostly consist
• macromolecules - biomolecules is also considered as macromolecules
• polymer - a long molecule that consists of several monomers, which are combined through covalent bonding
• 2 formulas in polymers

  • empirical formula
  • structural formula
• monomer - a single unit or building block from which a polymer is made
• empiricalformula - shows the simplest whole-number ratio of atoms of different elements in a compound
• structural formula - shows how the atoms are connected together in a molecule
• elements in biomolecules

  • carbon
  • oxygen
  • hydrogen
  • nitrogen
• carbon - is essential element of any living matter
• oxygen - the most abundant element in earths crust
• nitrogen - the most abundant element in earths atmosphere
• hydrogen - the simplest element known, having one proton and one electron
