A graph that describes the maximum amount of one good that can be produced for every possible level of production of the other good is nothing but a production possibilities curve.

Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another.. This bond generates two oppositely charged ions.

In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

Example ::

One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom. In this reaction, the sodium atom loses its single valence electron to the fluorine atom, which has just enough space to accept it. The ions produced are oppositely charged and are attracted to one another due to electrostatic forces.
