im not sure but ive got the egsact same question from my teacher miss cain, the little goody ratty greasy thing, erghhh, m i n g e r.

Ok, an atom is supposedly the smallest indivisible unit( at least in basic chemistry)

Now an atom is composed of 3 baser particles, Protons, Neutrons and electrons.

The Proton's are significant, since this is the particle that gives the atomic number to an element in the Periodic Table. It is also how a chemist defines an element. So for example 1 proton, is the atomic number 1, is the first element on the periodic table, and it is Hydrogen. Hydrogen uses the chemical symbol H

Second example 8 protons, is the atomic number 8, and is the 8th element on the periodic table, Oxygen is it's name. Oxygen uses the chemical symbol O.

Now for the formulae, H2O, is the chemical formula for Water, and the H stands for Hydrogen. The "2" symbolizes that you have 2 components (or atoms) of Hydrogen and the O stands for Oxygen. There is only one atom of Oxygen so it is just understood that with no number attached to the formula, that there is only the one atom.

So the formula H2O shows the elements that are combined to represent the water molecule. This allows a chemist who is trained to read the formula to easily understand the composition of the elements that make up the molecule.

What is the basic level of chemical organization?

The most basic level that elements are organized on the periodic table is according to their atomic number. Elements were originally organized purely by mass but this led to some inconsistency due to the occurrence of isotopes.
