Why does fluoride have 2 ions in the compound cadmium fluoride CdF2?
Wiki User
∙ 11y ago
The cadmium ion has a 2+ charge and each fluoride ion has a 1- charge, so two fluoride ions are needed to balance the 2+ charge of cadmium. Two F- ions provide a total negative charge of 2- to balance the 2+ charge of cadmium.

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.
What change will be caused by addition of a small amount of HCl to a solution containing fluoride ions and hydrogen fluoride?
The concentration of fluoride ions will decrease and the concentration of hydrogen fluoride will increase.
How many fluoride ions are present in 175 g of barium fluoride?
24
What are the symbols for the ions in magnesium fluoride?
magnesium fluoride is MgF2, Mg2+ F-
What is the correct interpretation of the formula MgF2?
The two elements that make up this compound are magnesium and fluorine. Flourine is a halogen and magnesium is an alkaline earth metal. This makes it an ionic compound, so the name would be magnesium fluoride.
What is the scientific name for the compound KF?
The scientific name for the compound KF is potassium fluoride. It is composed of potassium (K) and fluoride (F) ions.
Why lithium fluoride is a neutral compound even though it is made up of ions that have posotive and negative charges?
Lithium ions have a charge of +1 and fluoride ions have a charge of -1. The formula unit for lithium fluoride is LiF, which means that the lithium and fluoride ions are present in a 1:1 ratio. So the positive and negative charges cancel each other, and the compound lithium fluoride is neutral.
What happens when a lithium ion is attracted to an fluoride ion?
Lithium ions form bonds with fluoride ions to form an ionic compound: lithium fluoride (LiF).
Why do you need one zinc ion and two fluoride ions for zinc fluoride formula?
In any ionic compound the charges of the ions must balance out to zero. The zinc ion has a 2+ charge while the fluoride ion has a 1- charge. So zinc fluoride must contain two fluoride ions for every zinc ion.
Why do you need one zinc ion and two fluoride ions for the formula zinc 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.
What is the formula for the ionic compound formed from silver and flouride ions?
The chemical formula of silver fluoride is AgF.
Explain what the formula CaF2 tells you about this compound?
Ca+2 F-1 <----- these are the ions and their charges Ca+2 F-1 F-1 <----- the charges have to add up to zero, so two -1 fluorine ions cancel out one +2 calcium ions CaF2 <---- simplify
What change will be caused by addition of a small amount of HCl to a solution containing fluoride ions and hydrogen fluoride?
The concentration of fluoride ions will decrease and the concentration of hydrogen fluoride will increase.
How many fluoride ions in MgF2?
2 ions
What is an example of a Halides?
fluoride, chloride ions, bromide ions, iodide ions
What is AgF?
Silver ions and Fluoride ions put together.
