Is fluorine a gas?
Fluorine is an univalent poisonous gaseous halogen, it is pale yellow-green and it is the most chemically reactive and electronegative of all the elements.
It is so reactive that glass, metals, and even water, as well as other substances, burn with a bright flame in a jet of fluorine gas..
Is oxygen a cation or anion?
If the oxygen atom loses electrons, it becomes a positively charged cation. Oxygen is most stable as an ion when it gains 2 electrons to become O2-, an anion.
What is the charge of lithium ion?
1+Lithium is in the Alkali Metal group or 1A column. The atoms in this group form ions with a 1+ charge. Lithium ion’s charge is 1+.
Does fluorine form a cation or anion?
Does it form a cation or an anion? Fluorine forms an ion by accepting one electron from another element which gives it a -1 charge because it now has one more negatively charged electron than positively charged protons. This is called an anion because the element gained electron and is a negatively charged ion.
Is fluorine a toothpaste?
Fluorine is added to city water supplies in the proportion of about one part per million to help prevent tooth decay. Sodium fluoride (NaF), stannous(II) fluoride (SnF2) and sodium monofluorophosphate (Na2PO3F) are all fluorine compounds added to toothpaste, also to help prevent tooth decay.
What fluorine is used for?
It is also used to make sulfur hexafluoride, the insulating gas for high-power electricity transformers. In fact, fluorine is used in many fluorochemicals, including solvents and high-temperature plastics, such as Teflon (poly(tetrafluoroethene), PTFE).
Is Ca metal or nonmetal?
Calcium. The chemical element Calcium (Ca), atomic number 20, is the fifth element and the third most abundant metal in the earth’s crust. The metal is trimorphic, harder than sodium, but softer than aluminium. A well as beryllium and aluminium, and unlike the alkaline metals, it doesn’t cause skin-burns.

What is the symbol for fluorine?
Is Sulfur positive or negative?
Sulfur is in group 6 of the periodic table. What is the charge on its ions, and is the charge positive or negative? The charge is negative, since sulfur is a non-metal.
What Colour is fluorine?
pale yellowThe halogens become darker as you go down the group. Fluorine is very pale yellow, chlorine is yellow-green, and bromine is red-brown. Iodine crystals are shiny purple – but easily turn into a dark purple vapour when they are warmed up.
What ion would fluorine form?
Fluorine, F It has seven electrons in its outer shell. It gains an electron from another atom in reactions, forming a fluoride ion, F -. Note that the atom is called fluorine, but the ion is called fluoride. A fluoride ion has the same electronic structure as a neon atom (Ne).
What element has a charge of +2?

Is fluorine toxic to humans?
Fluorine gas is very irritating and very dangerous to the eyes, skin, and lungs. Fluorine gas at low concentrations makes your eyes and nose hurt. At higher concentrations, it becomes hard to breathe. Exposure to high concentrations of fluorine can cause death due to lung damage.
What does fluorine smell like?
Fluorine is usually a pale yellow gas. It has a pungent odor. It is far too dangerous to taste or feel.
Is fluorine a metal?
Fluorine is non-metal, it is a element with the symbol F and atomic number 9. It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. As the most electronegative element, it is extremely reactive, as it reacts with almost all other elements, except for helium and neon.
What is the formula for fluorine?
Is fluorine positive or negative?
A fluorine atom will tend to gain, rather than lose, an electron. By gaining a negative electron, it has an overall negative charge. It has become a negative ion. The positive lithium ion and the negative fluoride ion will now be attracted to each other.
