Fluorine appears as a very pale yellow-green gas and is in a gaseous state at room temperature ( 20☌). However, it still means that fluorine is unstable as it doesn’t exactly follow the ideal electron configuration.įluorine, being the 13 th most common element in the Earth’s crust is a dangerously reactive gas. Since the optimal configuration of the outer shell contains 8 electrons, fluorine is so close to the ideal electron configuration, such that the electrons are held very tightly to the nucleus. Fluorine has two outer shells, the first shell consisting of 2 electrons positioned directly opposite from each other, and the second shell consisting of 7 electrons evenly spaced out from each other in a circle. Since its atomic weight is 18.998 grams, it can be assumed that there are 10 neutrons within the nucleus of the atom. It has an atomic number of 9, meaning that it consists of 9 protons and 9 electrons. (Chem4Kids, 2016)įluorine (F) is the first element in the Halogen group (group 17) in the periodic table. & Marsden, S., 2015) There are a few common usage of Fluorine and this element can be found in a variety of items and objects including rocket fuel, refrigeration fluids and toothpaste (helps to prevent tooth decay). Given that it is the top element in the Halogen Group, it is the most electronegative element and therefore is very reactive. It is classified as a non-metal and is the first element in the family of halogen gases. This blog will include the following components: a 3D model of the atom Fluorine, a description on the composition, structure and characteristics of Fluorine, questions that I wish to investigate further and the difficulties that I experienced throughout the programming.įluorine is a chemical element represented by the symbol ‘F’ and has an atomic number of 9. Using a program called VRMath2.0, my group created a 3D model of fluorine which included the nucleus of the atom and its outer shells. The topic of this blog is going to be about an atom i.e.
