What part of the chemical equation tells the number of atoms of each element?

That depends on the nature of the reaction. For a typical reaction, it will be the subscript following the symbol of the element multiplied by the coefficient. For example, in Na2SO4 there will be 2 Na atoms, 1 S atom and 4 O atoms. If the reaction was 2 Na2SO4, there would be 4 Na atoms, 2 S atoms and 8 O atoms.

When a chemical reaction occurs atoms get ionized. Atoms are never created nor destroyed in a chemical reaction.


What does it mean to balance a formula?

To add atoms into a formula so that a chemical reaction will end with the same amount of atoms from the beginning. Ex. CH4 + 2O2 --> CO2 + 2H2O The law of conservation of mass states that matter cannot be created or destroyed, so if you end with CO2, all other atoms that were present before the reaction must also be present in the "after" formula; you have to add to either side so that there will be the same amount of atoms on both sides.


Can atoms be divided by chemical reaction?

No, this would be contrary to the definition of an ordinary chemical reaction.


What is the nuclear reaction called when atoms split?
