1 Anemometer: A tool used by meteorologists to measure wind speeds. 2  Speed: How fast or slowly something is moving.  Revolutions per minute (rpm): How many times something goes around in a complete circle, or rotates, in one minute. The anemometer you will make in this exercise measures the wind speed in rpm.
Electron acceptors participate in electron-transfer reactions. In this context, the oxidizing agent is called an electron acceptor and the reducing agent is called an electron donor. A classic oxidizing agent is the ferrocenium ion Fe(C. 5H.
An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron.
