Look at the chemical formula. NaCl is one atom of Na and one atom of Cl. NaCl is your common table salt. Water H2O, is two atoms of Hydrogen and one atom of Oxygen, H and O. Here is a link to a good table of elements
By comparing the number of protons it has to see which element on the Periodic Table has the same atomic number. Then, by finding the number of neutrons, you can determine the exact isotope.
Organic molecules contain carbon and have C-H (carbon-hydrogen) bonds.
Atoms are identified by either of following:
Symbol of the element
No of valence electrons and shells of the element
Proton.
The number of protons in an atom determines the identity of the element.See these two related questions for more information:[http://wiki.answers.com/Q/What_is_the_atomic_number_and_what_does_it_tell_you_about_the_number_of_protons_in_an_atomWhat is the atomic number and what does it tell you about the number of protons in an atom?]and[http://wiki.answers.com/Q/How_do_you_find_the_number_of_protons_and_electrons_and_neutrons_in_an_atomHow do you find the number of protons and electrons and neutrons in an atom?]
The flow of electrons from atom to atom is an electrical current.
The atom that gains electron becomes an anion. The atom that loses electron becomes a cation.

Atoms are normally identified according to the element of which that atom is an example. And that, in turn, is determined by the number of protons in the atom's nucleus. So, any atom that has just one proton is a hydrogen atom. If it has two protons it is a helium atom. And so forth.
