This stability is attained when the outer electron levels are full.
When the crystals dissolve in water, ions become free to move. Which type of chemical bond forms when electrons are either gained or lost by an atom? In this lab you will learn the rules behind naming chemical compounds, both ionic and covalent. Learning about ionic and covalent bonds is an important part of any introductory chemistry course, and finding out the differences between bonds gives you an insight into why different materials behave and react in distinct ways.
