A bond formed when atoms transfer electrons is a(n) ______ bond. The formation of ionic bond between two atoms can be visualized as follows: * An ionic bond is formed when the electronegativity difference between two bonding atoms is greater than 1.7 on Pauling's scale. Symbols that show the elements in a compound and the ration of atoms is a(n) _____. Ionic bonds form when two or more ions come together and are held together by charge differences. A chemical bond is what holds the atoms together and when bonds form, electrons are gained, lost or shared. They can often attain a completely filled outer electron shell more easily by transferring electrons to or from another atom than by sharing electrons. Therefore, ions combine in ways that neutralize their charges. Similarly, each calcium atom (group 2) can give up two electrons and transfer one to each of two chlorine atoms to form CaCl 2, which is composed of Ca 2+ and Cl − ions in the ratio of one Ca 2+ ion to two Cl − ions.
