Webions are formed. e.g. When sodium chloride (NaCl) forms, one electron is transferred from the outer orbit (shell) of the sodium atom into the outer orbit of the chlorine atom. This will form a full stable outer orbit (shell) for the two particles. The sodium atom becomes a positive sodium ion (Na+). The chlorine atom becoms a negative chloride ... Web6 dec. 2024 · Flame tests are used to identify the presence of a relatively small number of metal ions in a compound. Not all metal ions give flame colours. For Group 1 compounds, flame tests are usually by far the easiest way of identifying which metal you have got. diamond coach parts
