Atoms, Elements and Molecules

Question Guidelines:

It is helpful if your question is related to the work conducted at Jefferson Lab. The more unrelated your question is to the work done at Jefferson Lab, the less likely it is that we will be able to provide you with an answer. If you are unfamiliar with Jefferson Lab, take a look at our virtual tour to learn what we are all about.

Please do not submit a worksheet full of questions and expect us to provide you with the answers. While we will be more than happy to try to explain the concepts behind a problem or how to work a particular problem out, we will not do your homework for you. Please keep in mind that it may take as long as 5 working days to reply to your question. If your homework is due tomorrow, you probably will not receive an answer in time to be of much help.

Are you asking a question about an element? Have you looked at the Periodic Table of Elements yet? If you haven't, go there now! There is a lot of information on the Table of Elements listed for each element, including when it was discovered, who discovered it, its melting and boiling points, its density, some of its common compounds and some of its uses. Please, read about the element you are interested in before asking a question about it. Questions which can be answered by reading the Table of Elements will be responded to last.
