WebAug 15, 2024 · For an anion to form, one or more electrons must be gained, typically pulled away from other atoms with a weaker affinity for them. The number of electrons gained, and so the charge of the ion, is indicated after the chemical symbol, e.g. chlorine (Cl) gains one electron to become Cl-, whilst oxygen (O) gains two electrons to become O 2-. WebExplanation: The order is based on the tendency of the half-reaction to be reduced. Mg2+ has the highest tendency to be reduced and hence is the strongest reducing agent. Co2+ has the lowest tendency to be reduced and hence is the weakest reducing agent. Question 18: Number of electrons lost per atom of S: 4 Number of electrons gained per atom ...

WebA neutron is one of the subatomic particles that make up matter. In the universe, neutrons are abundant, making up more than half of all visible matter.It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1839 times greater than that of the electron.The neutron has a mean square radius of … WebWrite out half reactions to show how many electrons are gained or lost by each species.
