Hydrogen, helium, lithium, beryllium, etc. They are the configurations of atoms which, either alone or compounded with other elements, comprise the world around us. You can find the list all over the Net. There are 116 elements, as of last count. I remember reading that hydrogen makes up 95% of the matter in the universe, helium makes up 4%, and everything else added together is the final 1%. Those proportions could have been modifed since I studied it. And don't forget about dark matter... a whole new can of worms.
Hydrogen consists of a single proton and a single electron. The thing to remember is that the ADDITION OF 1 PROTON INCREASES THE ATOMIC NUMBER and results in a new element. The addition of neutrons helps the nucleus stick together and increases atomic weight, and can form different isotopes of an element, but DOES NOT change the atomic number.
The number of electrons generally matches the atomic number, which is the number of protons. If the number of electrons does NOT match, then you have a charged particle - but the element is the same either way.

http://www.chemtopics.com/elements.htm
(This one also contains links to many other sites with information on the elements)
