Chem chapter 3 notes 3-1 -There are two fundamental bonds that hold atoms together in a compound. -They are known as covalent bonds and ionic bonds. - Covalent bonds include sharing electrons between atoms and give rise to molecular compounds. -Ionic bonds involve a transfer of electrons from one atom to another. They give rise to ionic compounds. - A molecular compound is made up of units called molecules. They typically consist of a small number of nonmetal atoms held together by covalent bonds. -Molecular compounds are represented by chemical formulas, which are symbolic representations that indicate the elements present and the relative number of atoms of each element. - An empirical formula is a simple formula. The subscripts in an empirical formula are reduced to their simplest whole-number ratio. - A molecular formula shows the actual composition of a compound. - A structural formula shows the order in which atoms are bonded in a molecule and by what types of bonds. - A condensed structural formula is the same as what is seen above, but it is less cumbersome. -Organic compounds are made up of primarily carbon and hydrogen with oxygen and/or
