Calcium ion: Ca2+
Chloride ion: Cl-
Calcium (Ca) is an element in group 2, so would, when ionised, become Ca2+.
The First World War
Ca+2
it is 2 not 1
The chemical symbol (not formula) of calcium is Ca.
calcium cation = Ca2+ carbonate ion = CO32- the charges should cancel and you have the correct formula
The Chemical Formula for Calcium Citrate is Ca3(C6H5O7)2.
Ca2+
The chemical formula starts out with the two ions, the calcium and sulfide ions. Calcium's ion is Ca2+, while the sulfide ion is S2-. Because the net ionic charge of a compound is zero, only one of each atom is needed to create calcium sulfide, which will be CaS.
Calcium ion is Ca2+ and the carbonate ion is CO32-
The chemical symbol (not formula) of calcium is Ca.
This chemical formula is Ca3(PO4)2.
Ca^2+
This formula is Ca(OH)2.
Calcium selenide, CaSe, is formed.
The phosphate ion is (PO4)3-. Hence, Calcium phosphate is Ca3(PO4)2 as the Calcium ion is Ca2+)
Ca3(PO4)2
calcium cation = Ca2+ carbonate ion = CO32- the charges should cancel and you have the correct formula
The Chemical Formula for Calcium Citrate is Ca3(C6H5O7)2.
As calcium forms the 2+ ion, and hydroxide has a negative charge, the formula would be Ca(OH)2
The calcium ion is doubly positively charged (Ca2+) while the chloride ion is singly negatively charged (Cl-). Two chloride ions are required to balance one calcium ion in the ionic compound calcium chloride. Therefore its chemical formula is CaCl2.
