Question

Из атома, электронная конфигурация которого 2е,8е,8е,1е получается ион 2е,8е,8е Определите, что это за атом, какой ион, с каким зарядом он образует, кем является-окислителем или восстановителем? Почему?

Answer 1

Складываем все электроны, получаем 19, смотрим в переод. Таблицу - под номером 19 - калий. Ион положительно заряжен, т. к. потерян электрон. Ион является окислителем, так как заберёт недостающие электрон во время реакции

Answer 2

Atom and Ion Identification

The atom with an electronic configuration of 2e, 8e, 8e, 1e corresponds to Oxygen (O). The ion with an electronic configuration of 2e, 8e, 8e corresponds to Oxygen with a charge of -2e.

The atom with an electronic configuration of 8e, 4e, 14e corresponds to Iron (Fe). The ion with an electronic configuration of 8e, 4e, 14e corresponds to Iron with a charge of +3e.

Ion Charge and Reactivity

- The ion formed by Oxygen is Oxygen with a charge of -2e. This ion is known as an oxidizing agent because it tends to accept electrons from other substances, causing them to be oxidized. - The ion formed by Iron is Iron with a charge of +3e. This ion can act as a reducing agent because it tends to donate electrons to other substances, causing them to be reduced.

Explanation

The reactivity of an ion is determined by its ability to gain or lose electrons. In the case of Oxygen with a charge of -2e, it has a strong tendency to accept electrons, making it an oxidizing agent. On the other hand, Iron with a charge of +3e has a tendency to donate electrons, making it a reducing agent. These properties make Oxygen an oxidizing agent and Iron a reducing agent.

This behavior is based on the concept of oxidation and reduction in chemical reactions. Oxidation involves the loss of electrons, while reduction involves the gain of electrons. Substances that cause oxidation are called oxidizing agents, while substances that cause reduction are called reducing agents.

The reactivity of these ions makes them important in various chemical reactions and processes, including redox reactions and biological processes.
