Fluoride ions (F-), being a charge species, cannot exist on their own. The same is true of all ions.
They must be accompanied by a positive ion (such as Na+ or Ca2+) to balance their negative charge.
The substances collectively referred to as fluorides (sodium fluoride, calcium fluoride, etc.) are compounds.

How many fluoride ions in MgF2?
There are two fluoride ions in magnesium fluoride (MgF2), as the formula indicates the ratio of magnesium ions (Mg2+) to fluoride ions (F-) is 1:2.
How many fluoride ions are in 1.46 moles of aluminum fluoride?
There would be 4.38 moles of fluoride ions in 1.46 moles of aluminum fluoride, as the formula for aluminum fluoride is AlF3 with three fluoride ions per molecule of aluminum fluoride.
What are the ions for calcium fluoride?
The individual ions for calcium fluoride have the formulas Ca+2 and F-1 respectively. That means that in any sample of calcium fluoride, there must be twice as many of the fluoride ions.
How many fluoride ions are present in 175 g of barium fluoride?
To determine the number of fluoride ions in 175 g of barium fluoride, first calculate the number of moles of barium fluoride using its molar mass. Then, use the ratio of fluoride ions to barium fluoride in the formula BaF\u2082 to find the number of fluoride ions. Finally, multiply this by Avogadro's number (6.022 x 10^23) to get the total number of fluoride ions.
How many ions are in carbon fluoride?
In a compound such as carbon fluoride, the number of ions present depends on the ionic form of the elements. For example, carbon typically forms covalent bonds and does not usually exist as an ion, while fluoride ions have a charge of -1. So, in a compound like carbon fluoride (CF₄ or CF₂), there are no ions of carbon but four fluoride ions for CF₄ and two fluoride ions for CF₂.
How many Fluoride ions are there per unit cell in solid barium fluoride?
In solid barium fluoride (BaF2), there are four fluoride ions per unit cell.
What elements make lithium fluoride?
Lithium fluoride is composed of lithium ions (Li+) and fluoride ions (F-). Each lithium ion is surrounded by four fluoride ions in a tetrahedral arrangement, creating a lattice structure. This compound is held together by ionic bonds due to the attraction between the positively charged lithium ions and the negatively charged fluoride ions.
How many calcium ions and fluoride ions take to make up an ionic crystal?
In an ionic crystal of calcium fluoride (CaF₂), one calcium ion (Ca²⁺) pairs with two fluoride ions (F⁻) to maintain charge neutrality. This means that for every calcium ion, two fluoride ions are needed, resulting in a 1:2 ratio of calcium to fluoride ions in the crystal lattice.
Is fluoride an example of a cation?
No, fluoride is an anion, not a cation. Cations are positively charged ions, while anions are negatively charged ions. fluoride has a negative charge, making it an anion.
What is an example of a Halides?
fluoride, chloride ions, bromide ions, iodide ions
What is AgF?
Silver ions and Fluoride ions put together.
Two elements of magnesium fluoride?
Magnesium fluoride is a compound composed of magnesium and fluoride ions. In its crystal structure, magnesium atoms are surrounded by fluoride ions and vice versa. This compound exhibits a high melting point due to the strong ionic bonds between magnesium and fluoride ions.
