What kind of bond is formed when one atom steals an electron from another atom
Delicious77 [7]
Ionic bonds <span>are the type of bonds where there is </span>transfer<span> of electrons from one atom to another.  The electrons are removed and from one atom and attached to  another. A good example is salt which is composed of sodium and chlorine. Sodium readily loses one of its electrons and chlorine readily accepts it. Before losing the electron, sodium has a positive charge, but then becomes negatively charged after giving up the electron. Chlorine has a positive charge before gaining the electron but becomes negatively charged after gaining the electron. These opposite charges between sodium and chlorine attract the two elements together to form the ionic bond.</span>
