atoms & molecules

What is the difference between an atom and a molecule? What is an example of each?

[engaaraa]

An atom is the most elementary entity of a chemical element. A molecule is a combination of atoms linked together. For example Helium is almost always a lonely atom, and hydrogen is usualy a molecule made up of two hydrogen atoms.

I really suggest you read your textbook if you want to pass your class.

Besides; if you give the answers we give you, it will be noticable it wasn't you. You have to be able to answer the question with your own words. If you can do that, and you still can do that in a month from now, you've actually learnt something! :p :p
