## Chemical Bonds: Elements that do not readily participate in chemical processes are said to be inert. For example, helium, neon, and argon have filled outermost energy levels. These elements are called inert gases, because their atoms neither react with one another nor combine with atoms of other elements. On the other hand, elements with unfilled outermost energy levels, such as hydrogen and lithium, as discussed earlier, are reactive, because they readily interact or combine with other atoms. In doing so, these atoms may achieve stability by any of the following: 1. Gaining electrons 2. Losing electrons 3. Sharing electrons The interactions of these atoms involve the formation of chemical bonds, which hold the participating atoms together once the reaction has ended. We will consider three basic types of bonds. 1. Ionic bond 2. Covalent bond 3. Hydrogen bond Notes:
