What is the chemical reaction of fluorine?
Fluorine decomposes in water to form hydrofluoric acid (HF), hydrogen peroxide (H2O2) and oxygen fluoride (OF2) (1). Fluorine gas is a powerful oxidizing agent that combines directly with many gases and liquids (sometimes violently) to form a variety of fluorine compounds (1,2). The elemental form of fluorine, a pale yellow-green, irritating gas with a sharp odor, is so chemically reactive that it rarely occurs in the environment in the elemental state (3).
How to know if you are exposed to fluorine?
Warning: Fluorine is a corrosive gas and may be converted to hydrofluoric acid in the lungs and on other moist tissue. Signs and Symptoms of Fluorine Exposure: Signs and symptoms of acute exposure to fluorine include coughing, choking, and chills. Eye, nose, skin, and respiratory irritation may occur. Eyelid eczema and thermal burns have been noted after dermal contact. In severe exposures, pulmonary edema may develop after 1 to 2 days. Emergency Life-Support Procedures: Acute exposure to fluorine exposure may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination. Inhalation Exposure: 1. Move victims to fresh air. Emergency personnel should avoid self-exposure to fluorine. 2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support. 3. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures. 4. Transport to a health care facility. Dermal/Eye Exposure: 1. Remove victims from exposure. Emergency personnel should avoid self-exposure to fluorine. 2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer oxygen or other respiratory support. 3. Remove contaminated clothing as soon as possible. 4. If eye exposure has occurred, eyes must be flushed with copious amounts of lukewarm water for at least 15 minutes. 5. Wash exposed skin areas thoroughly with soap and water. 6. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures. 7. Transport to a health care facility. Ingestion Exposure: Not applicable. (EPA, 1998)
What happens when water vapor reacts with fluorine?
Water vapor will react combustibly with Fluorine; an explosive reaction occurs between liquid fluorine and ice, after an intermediate induction period, [NASA SP-3037: 52 (1967)]: If liquid air, which has stood for some time is treated with Fluorine, a precipitate is formed which is likely to explode. Explosive material is thought to be Fluorine Hydrate, [Mellor 2:11 (1946-1947)]. It reacts with water to form hydrofluoric acid and oxygen.
How are fluorides and hydrogen fluoride related?
Fluorides, hydrogen fluoride, and fluorine are chemically related. Fluorine is a naturally-occurring, pale yellow-green gas with a sharp odor. It combines with metals to make fluorides such as sodium fluoride and calcium fluoride, both white solids. Sodium fluoride dissolves easily in water, but calcium fluoride does not. Fluorine also combines with hydrogen to make hydrogen fluoride, a colorless gas. Hydrogen fluoride dissolves in water to form hydrofluoric acid. Fluorine and hydrogen fluoride are used to make certain chemical compounds. Hydrofluoric acid is used for etching glass. Other fluoride compounds are used in making steel, chemicals, ceramics, lubricants, dyes, plastics, and pesticides. Fluorides are often added to drinking water supplies and to a variety of dental products, including toothpaste and mouth rinses, to prevent dental cavities.
What is the difference between hydrogen and fluorine?
Fluorine also combines with hydrogen to make hydrogen fluoride, a colorless gas. Hydrogen fluoride dissolves in water to form hydrofluoric acid. Fluorine and hydrogen fluoride are used to make certain chemical compounds. Hydrofluoric acid is used for etching glass.
How does fluorine act as a poison?
Fluorine and fluorides act as direct cellular poisons by interfering with calcium metabolism and enzyme mechanisms.
What is the average fluorine concentration in coal?
Monitoring of atmospheric emissions from two coal-fired power plants found median fluorine concentrations of 0.3-3 ppm (1).
What is the chemical shortcut for HCl?
HCl is the chemical shortcut for Hydrochloric acid, a compound of hydrogen (H) and chlorine (Cl).
How many electrons does a hydrogen atom have?
Single hydrogen atom contains 1 electron which is free electron i.e valance 1 and anything that is valence 1 is highly unstable. They have two option either to give up free electron or take 1 electron from neighboring hydrogen atom to fill its orbital ( which is 2 in this case ) .
How many atoms are in a compound?
ALL compounds are molecules because they HAVE to have at least 2 DIFFERENT elements, so they must have at least 2 atoms (unless you want to be technical about ionic compounds like NaCl which are actually called “formula units”) (H2O, NH3, CH4, CO2, C6H12O6, NaCl, etc.).
What is the effect of the nucleus on the electrons of each atom?
The nucleus of each H atom exerts an attractive force on the other’s electron and “shares” the electron with each other. This results in the formation of a molecule made up of atoms, rather than an ionic compound that is made up of ions. Related Answer.
What is an element?
Element: An element is a simplest atom or molecule, which cannot be broken down. For example: H2, O2, etc. Compound: A Compound is made up of combination of elements. For example: (H2O), NaCl, etc. Mixture: A mixture is made up of combination of compounds. For example: Mixture of salt and water, air etc. 6.1K views.
How are compounds formed?
Compounds are formed when two or more atoms of DIFFERENT elements combine chemically.
What are elements that are atoms?
There are elements that are atoms (U, Fe, Ne, C, Cu, He, Ar, etc.).
How many electrons do atoms seek in their valence shell?
Several atoms tend to seek eight electrons in their valence shell through chemical bonding; this is referred to as the octet rule and is reflected in the Lewis structure of a molecule.
What are the three unshared pairs of electrons on each fluorine atom called?
The three unshared pairs of electrons on each fluorine atom are called the lone pairs. Step 3. Now, let us construct a skeleton of the F2 molecule on the basis of the information presented in step 2. Both fluorine atoms share one pair of electrons and hence have a single covalent bond between them.
Which atoms have the same energy?
In a fluorine atom, the valence orbitals—2s, 2px, 2py, and 2pz—hybridize together to form four identical sp3 orbitals, all of which have the same energy.
When the valence orbitals on two atoms in a molecule overlap by sharing a pair of?
When the valence orbitals on two atoms in a molecule overlap by sharing a pair of electrons, a chemical bond is said to form between the two atoms.
Where does the required electron come from?
This required electron comes from the half-filled sp3 hybrid orbital from the second fluorine atom. This results in the formation of a single bond (also called sigma bond) between the half-filled sp3 hybrid orbitals of two fluorine atoms. The already fully filled sp3 hybrid orbitals on each atom are the lone pairs.
Why do the shapes of Sigma and Pi vary?
The shapes of sigma and pi orbitals vary, and so do the shapes of sigma* and pi*, because of the difference in the ways the constituent atomic orbitals overlap. Note that there are 8 atomic orbitals mixing to form 8 molecular orbitals.
Which electrons are involved in bonding?
The valence electrons in each atom are the ones that participate in the bonding, and hence they are the only ones displayed in the Lewis structures. It is to be noted though that this theory about the electronic structure is quite primitive and most limited.
