WebIons are formed when atoms or molecules lose or gain electrons; therefore, ions have an overall positive or negative charge. If an atom or a molecule loses an electron → positively charged ion If an atom or a molecule gains an electron → negatively charged ion As we already know, solution results from a solute that is dissolved in a solvent.

WebF - ion Answer 1: The atomic number of a magnesium atom is 12 and the mass number is 24. Therefore the number of protons in a Mg2+ ion is also 12 – the number of protons does not change when an ion is formed Number of neutrons = mass number – number of protons Number of neutrons = 24 – 12 Number of neutrons = 12 WebApparatus List.

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 ...
