Mass number = number of protons + neutrons They are important because they have negative electric charge and they assist in chemical bonding because of their interaction with adjacent nuclei. A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The role of valence electrons is to transfer between the atoms to make the atom stable. Anion is an atom which has more electrons than the protons and therefore has negative charge (for example Cl-). In later chapters, we will develop the concepts introduced here to explain why the only compound formed by sodium and chlorine is NaCl, an ionic compound, whereas neon and argon do not form any stable compounds, and why carbon and hydrogen combine to form an almost endless array of covalent compounds, such as CH, status page at https://status.libretexts.org.
