    conducting surface with a thin layer (seldom more than 0.001 in [0.025 mm] thick) of metal by electrolytic deposition. In electroplating‚ the object to be plated is made the cathode in an electrolytic bath of salts of the metal to be plated. The anode may be an unaffected metal‚ or‚ more commonly‚ the metal to be plated. An electriccurrent is passed through the solution‚ which results in the deposition of a thin metal plating in the desired thickness on the cathode. Traces of organic materials are usually

    Module One: Grade Nine Topics Physical Change: This is a usually reversible change in which the form of matter is altered‚ but is not chemically changed to another substance. Melting an ice cube is an example of a physical change. The ice cube changes states: from a solid to a liquid (water). You can physically see this change. No new substance is formed: the matter in the liquid is the same as it was in the ice cube. It is reversible: you can freeze the liquid to turn it back to ice.

    attraction between two oppositely charged ions. Ionic bonds are formed between an metal and a non-metal. The metal loses an electron or electrons form its highest energy level becoming a positively charged Ion and the non-metal gains an electron or electrons in its highest energy level‚ becoming a negatively charged Ion. Covalent bonds are strong bonds between two non-metal atoms. A covalent bond forms when two non-metal atoms share a pair of electrons. The electrons involved are in the highest occupied

    Lithium‚Sodium‚Potassium‚Rubidium‚Caesium and Francium are all part of group 1.They are metals that can be easily cut.After being cut‚it is shiny but it quickly tarnishes due to the fact that the metal reacts quickly with oxygen or water.The shiny surfaces of Sodium quickly tarnishes more quickly than Lithium and Potassium more tarnishes more quickly than Lithium.This shows that the reactivity increases as we move down the group.

    experiment is to study a set of metals and their reactions reactions using different metals in an ordered activity series‚ the goal is to find the relative reactivity of them.Discovering why metals react with certain cations and solutions is the main point of this lab. This has many real life applications. When creating buildings‚ or bridges it is important to understand and counter-act the rusting of iron. You can do that by using the activity series. For any industry using metals‚ this is important. Manufacturing

    beating‚ paintless gouge evacuation is accomplished without harming the current paint on the metal‚ and can offer magnificent results at a small amount of the expense of different strategies for mark expulsion. The mystery behind paintless gouge repair is that as opposed to being a forceful strategy for fixing marks in the metal‚ it is a slow procedure more likened to a back rub than a bit of conventional metal work.

    opposite charge of cation and anion attract one another due to the electrostatic force which is formed between them. The formation of a ionic bond involves a metal and a non-metal. Thus it forms the ionic bond. (A) EXAMPLE OF IONIC BOND (1) Sodium Chloride Sodium chloride is an ionic compound formed by the reaction between the metal sodium and non-metal chlorine. During the reaction one electron is transferred from each sodium atom to each chlorine atom. Sodium atom with an electron arrangement of 2
