網頁Atoms and Ions: Difference. Atoms are the building blocks of all matter whereas an ion is a charged atom, i.e. an atom which has lost or gained one or more electrons in it (in which case it carries net positive or negative charge respectively). The number of protons in atoms is equal to the number of electrons, but for ions the number of ... 網頁Electron transfer between lithium (Li) and fluorine (F). Forming an ionic bond, Li and F become Li+ and F− ions. An ion (/ˈaɪ.ɒn, -ən/)[1] is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is ...
