Calcium Chloride
Ca (calcium) is an element, not a compound. and it can only form ionic compounds.
The chemical formula of calcium nitride is Ca3N2.
Ca(2+) and Br- are common ions; the neon ion probable doesn't exist.
Calcium Chlorite (used in domestic Swimming Pools)
Ca(ClO2)2 is the chemical formula of calcium chlorite.
Calcium would form Ca2+ and chlorine would form Cl-. The ionic compound would be CaCl2 to ensure a neutral charge for the whole compound.
a compound
Ca (calcium) is an element, not a compound. and it can only form ionic compounds.
The bond between calcium and sulfur would be ionic. The corresponding compound would be calcium sulfide.
Calcium Chloride
Calcium and sulfur will react in a 1:1 ratio to form calcium sulfide with the formula CaS.
When these two elements form an ionic compound (either with each other or with any other elements) then those are the ions that they form, Ca+2 and F-1.
We know that the alkaline earth metal calcium (Ca) and the halogen bromine (Br) form the ionic compound calcium bromide (CaBr2). Here's the reaction: Ca + 2Br => CaBr2
CaF2
All the alkali and alkaline earth metals: Li, Na, K, Rb, Cs, Fr, Ra, Ba, Sr, Ca, Mg, and Be. Most other metals would also form an ionic compound with fluorine.
20.0g Ca + 16.0g S = 36.0g CaS % Composition of Ca = 20.0g Ca/36.0g CaS x 100 = 55.6% Ca
