Bonding Basics You must first learn why atoms bond together. We use a concept called "Happy Atoms." We figure that most atoms want to be happy, just like you. The idea behind Happy Atoms is that atomic shells like to be full. That''s it. If you are an atom and you have a shell, you want your shell to be full.

Calcium hardness must be actively managed—along with pH and total alkalinity—to keep water in proper chemical balance. Understanding Calcium Hardness Reader note: An edited version of this article originally appeared in the summer 2007 issue of The Edge, a publiion of the Northeast Spa & …
Ionic compounds are compounds formed between a metal and nonmetal which have a crystalline lattice structure. They can conduct electricity and are usually highly water soluble. The ionic compounds can form one cohesive compound, such as Potassium Fluoride, or form more complex polyatomic ionic compounds, such as Calcium Carbonate.
In the written form, while the ion name is generally the same as the element, the suffix of single-atom anions is changed to –ide, as in the case of sodium chloride. If the anion is a polyatomic ion, its suffix can vary, but is typically either – ate or – ite, as in the cases of sodium phosphate and calcium nitrite, depending on the identity of the ion.

The maximum solubility of calcium oxide in calcium chloride at temperatures relevant to the reduction of PuO2 is about 21 mol% CaO.The ternary liquidus diagram of the CaO-CaCl2-KCl system has been
The chlorine atom has a higher electronegativity than the hydrogen atom, so the bonding electrons will be closer to the Cl than to the H in the HCl molecule. Difference in electronegativity 4.0 1.7 .4 0
Calcium is a mineral that is found naturally in foods. Calcium is necessary for many normal functions of the body, especially bone formation and maintenance. Calcium can also bind to other minerals (such as phosphate) and aid in their removal from the body.
Sodium chloride (NaCl). The most familiar use of sodium chloride is as a flavor enhancer in food. It is best known as table salt. Large amounts of sodium chloride are also added to prepared foods, such as canned, bottled, frozen, and dried foods
A library of different metal–ion crosslinked AHG beads was prepared according to the above-described procedure by using six gelling metals (i.e., Ca 2+, Cu 2+, Co 2+, Ni 2+, Zn 2+ and Fe 3+). 21,23 In all cases, metal chloride salts were used in order to avoid −

Flame tests are used to identify the presence of a relatively small nuer of metal ions in a compound. Not all metal ions give flame colors. For Group 1 compounds, flame tests are usually by far the easiest way of identifying which metal you have got.
