number of protons
number of electrons
number of atoms

The equation for photosynthesis is: 6H2O + 6 CO2 --> C6H12O6 + 6O2 The numerals in each part of the equation (without balancing it) mean: H2 = 2 atoms of Hydrogen O = 1 atom of Oxygen } H2O=water C = 1 atom of Carbon O2 = 2 atoms of Oxygen } CO2= Carbon Dioxide C6 = 6 atoms of Carbon H12 = 12 atoms of Hydrogen O6= 6 atoms of Oxygen } C6H12O6 } Glucose O2 = 2 atoms of Oxygen } O2 = Oxygen When balanced: 6H2O = 6 molecules of water 6CO2 = 6 molecules of Carbon dioxide C6H12O6 = Glucose 6O2 = 6 molecules of Oxygen.
