The diagram above shows Sodium Chloride being formed by the exchange of one electron. Notice that once the chlorine and sodium ions bond, the net charge becomes 0. What is a chemical bond? It is the bond formed between different elements share or exhange electrons which essentially "bonds" them together! * This week we learned the important concept that compounds are formed when chemical reactions occur. We also learned that when chemical reactions occur, electrons are exchanged (ionic compound) or are shared (molecular compounds) between the elements in a compound. We also reviewed the idea that in a mixture, there is no chemical bonds between the different substances.
