A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. Answer: Understanding bonding is important for understanding molecules because a molecule cannot exist without the bond between atoms. The waves and particles are the two common properties that electrons have. Each of the electron shells ( n1 to n7, or K to Q) can hold a maximum number of electrons determined by the formula: electron capacity = 2n 2 (where n is the electron shell number), as shown below. Facts about Electrons 1: the properties.
