At room temperature fluorine is a faintly
yellow gas with an irritating odour. Inhalation
of the gas is dangerous. Upon cooling fluorine
becomes a yellow liquid. There is only one
stable isotope of the element, fluorine-19.

How did you do?

• If you drew your models correctly, congratulations!

• If you made several mistakes, go back
over your notes, ask questions, check your
textbook, then try these again.
