Fluorine (F) is the first element in the Halogen group (group 17) in the periodic table. ... It is a nonmetal, and is one of the few elements that can form diatomic molecules (F2).

Why is fluorine a non-metal?
Answer: It has outermost electrons as 7, hence it prefers to gain one more electron to attain octet. Metals on the other hand, are ductile, malleable, conductors of heat and electricity etc. ... Hence, Fluorine is a non-metal.
Is fluorine a gas?
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.
What is Fluorine on the periodic table?
Fluorine: a small yet very adaptable element
The most reactive, electronegative and oxidizing element, fluorine (F) is the first halogen in the periodic table. Fluorine is naturally present in the Earth's crust where it is chiefly found in mineral form.
Is germanium a metal nonmetal or metalloid?
Most elements are either metals or nonmetals. Germanium falls in the same group as carbon and silicon, but also as tin and lead. Germanium itself is classified as a metalloid.
Which is not a metalloid?
Carbon is not a metalloid and is a non-metal. Metalloids are those elements possessing properties between non-metals and metals. These are also known as semi-metals. The elements which are metalloids, in the periodic table are boron, silicon, arsenic, antimony, polonium, and tellurium.
Which of the following is a metalloid?
Boron, silicon, germanium, arsenic, antimony, and tellurium are commonly recognised as metalloids.
Is Caesium a metal?
Caesium is a soft, gold-coloured metal that is quickly attacked by air and reacts explosively in water. The most common use for caesium compounds is as a drilling fluid.
Is fluorine a cation?
If we observe the pKb values (i.e. Group 7 atoms called halides, which include such elements as fluorine, chlorine, bromine and iodine, form anions with a charge of negative one. Anions have a negative charge, and cations have a positive charge.
Why is fluorine a anion?
If atoms lose electrons, they become positive ions, or cations. If atoms gain electrons, they become negative ions, or anions. ... A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.
Are halogens cations or anions?
Halogens always form anions, alkali metals and alkaline earth metals always form cations.
Is fluorine a mixture?
Fluorine is a chemical element with the symbol F and atomic number 9.
Is fluorine a mineral?
Fluorine is obtained mainly from the mineral fluorite or fluorspar (calcium fluoride). Other fluorine-bearing minerals include apatite and cryolite. It is mined in China, Mongolia, Russia, Mexico and South Africa.
Why is fluorine a gas?
In fluorine, the electrons are tightly held to the nuclei. The electrons have little chance to wander to one side of the molecule, so the London dispersion forces are relatively weak. ... At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases.
