We find the alkaline earth metal calcium in Group 2 of the Periodic Table. It "lives" there because it has two valence electrons. The nature of calcium is that it would really like to loan out those two electrons in an attempt to emulate the electron configuration of an inert or noble gas. Because it wants to loan out those two electrons, it has a "desire" to participate in chemical reactions.
To cite a single example of what calcium wants to do, let's combine it with chlorine in a chemical reaction. We know that chlorine is one electron short of a full valence shell, so this element wants to borrow an electron if it can. As calcium wants to loan out two electrons and chlorine wants to borrow one, they will react. Calcium and chlorine form calcium chloride. But there is bit more to the story.
An atom of calcium has two valence electrons to loan out, while chlorine wants to borrow only one. That means that twochlorine atoms will react with one calcium atom to make calcium chloride. Here's the reaction:
Ca + 2Cl => CaCl2
We've written the balanced chemical equation for the reaction of calcium with chlorine. Note that the 2 in front of the Cl on the left side of the equation appears as a subscript with the Cl on the right hand side of the equation. Our equation is correct.
It could be argued that chlorine appears as Cl2 in its elemental state. (This is dichlorine, a diatomic molecule.) In that case, we'd have to adjust our equation to balance it, and it would appear like this:
2Ca + 2Cl2 => 2CaCl2
Calcium forms a simple ion known as the calcium ion, which has a charge of +2. This occurs when a calcium atom loses two electrons, resulting in the ion denoted as Ca²⁺. This positively charged ion is commonly found in various compounds and plays essential roles in biological processes and chemical reactions.
The smallest particle of calcium that retains the chemical properties of calcium is the calcium ion (Ca2+). This ion has lost two electrons from a calcium atom, giving it a positive charge while maintaining the chemical characteristics of calcium.
The valence electrons are the part that takes place in a chemical reaction.
Di-sodium calcium phosphate. The PO4 ion has four missing valence electrons; it would be happy to replace them, and it does by sharing four pairs of electrons to form four chemical bonds: two with Ca++ and two with Na+ two times.
Calcium will lose two electrons to form Ca2+ cation.
Calcium ion is Ca2+ and the carbonate ion is CO32-
Calcium Sulphate and water. The easy way to see this is that you have an acid reacting with an alkali (hydroxides are always alkalis), so the reaction is a neutralisation reaction, meaning that it produces water. This leaves a sulphate ion and a calcium ion, which react to form the salt calcium sulphate.
The reaction between sulfamic acid and calcium carbonate produces calcium sulfamate, water, and carbon dioxide. This is a double displacement reaction where the carbonate ion in calcium carbonate exchanges places with the sulfate ion in sulfamic acid.
The formula for calcium ion is Ca^2+ and for phosphate ion is PO4^3-. When these ions combine, they form calcium phosphate (Ca3(PO4)2).
Yes, calcium nitrate will react with hydrochloric acid (HCl) to form calcium chloride, nitric acid, and water. This reaction is a double displacement reaction where the nitrate ion from calcium nitrate switches places with the chloride ion from hydrochloric acid.
The Li2- ion is unstable in this chemical reaction.

Yes, it is a (insoluble) salt (called limestone), chemical formula CaCO3.
When calcium (Ca) reacts with sulfur (S), they form calcium sulfide (CaS), a compound where one calcium ion is bonded to one sulfur ion through an ionic bond. The chemical formula for this compound is CaS.
The correct chemical formula for the reaction between Ca^2+ and NO2^- is Ca(NO2)2. In this reaction, the calcium ion (Ca^2+) combines with two nitrite ions (NO2^-) to form calcium nitrite.
