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.
Electron shell is a group of atomic orbital, so that their orbits formed electron shell with the same value of the principal quantum number. The 1, 2, 3, 4 electron shell can hold 2, 8, 18, 32 electrons respectively, since the electrons are electrically attracted to the nucleus.
