What happens to a stream of alpha particles that is shot at a thin sheet of gold foil?

Physicist Ernest Rutherford established the nuclear theory of the atom with his gold-foil experiment. When he shot a beam of alpha particles at a sheet of gold foil, a few of the particles were deflected. He concluded that a tiny, dense nucleus was causing the deflections.

Which element can be used as an oxidising agent and why?

Common oxidizing agents are oxygen, hydrogen peroxide and the halogens. In one sense, an oxidizing agent is a chemical species that undergoes a chemical reaction in which it gains one or more electrons. In that sense, it is one component in an oxidation–reduction (redox) reaction.

Can a molecule be an oxidizing agent?

Atoms, ions, and molecules that have an unusually large affinity for electrons tend to be good oxidizing agents. Elemental fluorine, for example, is the strongest common oxidizing agent. F2 is such a good oxidizing agent that metals, quartz, asbestos, and even water burst into flame in its presence.

Can water act as an oxidizing agent?

In the presence of a strong electron donor (strong reducing agent), water serves as an oxidizing agent. Water is rather weak as an oxidizing or as a reducing agent, however; so there are not many substances which reduce or oxidize it. Thus it makes a good solvent for redox reactions.

How do you find the oxidizing agent and reducing agent?

Break the reaction down into a net ionic equation and then into half-reactions. The substance that loses electrons is being oxidized and is the reducing agent. The substance that gains electrons is being reduced and is the oxidizing agent.

Is h202 an oxidizing agent?

Hydrogen peroxide is both an oxidizing agent and reducing agent. The oxidation of hydrogen peroxide by sodium hypochlorite yields singlet oxygen. The net reaction of a ferric ion with hydrogen peroxide is a ferrous ion and oxygen.

Can H2O2 act as a reducing agent?

Hint: Hydrogen peroxide behaves as oxidizing as well as reducing agents in both acidic as well as alkaline solutions.

What if the plum pudding model was correct?

If the plum pudding model had been correct then all of the fast, highly charged alpha particles would have whizzed straight through undeflected. most of the alpha particles did pass straight through the foil. a small number of alpha particles were deflected by large angles (> 4°) as they passed through the foil.
