A binary ionic compound is composed of ions of two different elements - one of which is a metal, and the other a nonmetal. For example, sodium iodide, NaI, is composed of sodium ions, Na + (elemental sodium is a metal), and iodide ions, I-(elemental iodine is a nonmetal).
The statement best describing an ionic bond is the following: "An ionic bond involves a metal that transfers one or more electrons to a nonmetal". This statement means that the metal will transfer
Calcium The chemical element Calcium (Ca), atomic nuer 20, is the fifth element and the third most abundant metal in the earth’s crust. The metal is trimorphic, harder than sodium, but softer than aluminium.A well as beryllium and aluminium, and unlike the alkaline metals, it doesn’t cause skin-burns.
To the left of the metal–nonmetal dividing line, such elements include gallium, tin and bismuth. They show unusual packing structures,  marked covalent chemistry (molecular or polymeric),  and amphoterism.
