Like other halogens, molecular fluorine is highly dangerous; it causes severe chemical burns on contact with skin. Fluorine is less common in stars than on Earth, where it is the 13th most frequently found element in the crust.    Metalloids  Comments Copyright © 1996-2012 Yinon Bentor. Have any problems using the site? In its pure form, it is a poisonous, pale, yellow-green gas, with chemical formula F2.
