2011/1/25· Non-metals, on the other hand are not conductors of such and gain electrons and turn into anions once they undergo chemical changes. Also, non-metals can be either solid, liquid, or gas and come in a variety of colors. They are brittle and non stretchable or
Aluminum is a shiny grey metal and has a clear oxide that forms on contact with air. This may not be the best thing for identifying it, but aluminums melting point is 658 C (1217 F). Also aluminum is non sparking. Aluminums density is 2.70 g/cm 3, this is a good way to identify it because you can find the density of a material by density = mass ÷ volume.

The Group 0 NOBLE GASES consist of helium, neon, argon, krypton, xenon and radioactive radon. The physical properties are described and the group trends in melting points, boiling points and atomic radii and also the ''few'' chemical properties are mentioned.
In the reactivity series, as we move from bottom to top, the reactivity of metals increases. Metals present at the top of the series can lose electrons more readily to form positive ions and corrode or tarnish more readily. They require more energy to be separated from their ores, and become stronger reducing agents, while metals present at the bottom of the series are good oxidizing agent.
