Fluorine is an element and its atomic number is 9. It comes under the group of Halogens. It is highly dangerous and is found in the form of fluorine gas. The color of the gas is yellowish brown and it is extremely poisonous. I suggest that your daughter can make a shell diagram of fluorine in which she can show the electronic arrangement in fluorine. I am uploading the model of fluorine please view it. Best of luck for your daughter :)
