Here is an isotope question to challenge your wits.
Naturally occurring nitrogen consists of two isotopes 14N and 15N.
How many different nitrogen molecules will
occur in the air?
If you need help post a message on the board.

The answer here is 3. There can be three possible molecule combinations containing the two types of nitrogen isotope.
14N - 14N
14N - 15N
15N - 15N
Hope this helps you out.
