used. As you will recall from previous chapters‚ a diode is a check valve for electrical current. Current may flow only in one direction through a diode. It obtains its name from di-‚ meaning two‚ and -ode for electrodes. The electrodes are named the anode (positive electrode) and cathode (negative electrode). There are many different kinds of diodes. We will restrict ourselves here to just two types‚ germanium and silicon. The only differences between the two that are significant to us will be the:

IGSCE Chemistry Notes Oxides Oxides are used to determine whether an element is a metal or a non-metal. Most non-metals are classed as acidic oxides. While most metals are classed as basicoxides. Acidic Oxides * Reacts with water to form acids * Neutralises alkaline solution to form salt + water Basic Oxides * Neutralises acidic solutions to form salt + water Amphoeteric Oxides * These are non-metals which display both acidic and basic properties Alkaline Oxides * Reacts

thin coating of zinc oxide. The purpose of the zinc is to protect the steel from elements that normally would lead to oxidation‚ corrosion and the eventual weakening of the steel. In this sense‚ the zinc coating acts as what is called a sacrificial anode. In other words‚ the zinc will protect the steel from corrosion by acting as a barrier between the steel and the corrosive agent; at least until the zinc coating has been completely oxidized. Zinc plating involves the electrolytic application of zinc
