Rust treatment Featured 14 Sep 2004 Print

Rust treatment

Rust treatment. Brush being used to apply a rust removing mix of chemicals to a rusty spanner. Many commercial mixes of chemicals are available to remove rust (iron oxide). Most of them use strong acids, so skin contact should be avoided. If left, the acids will also corrode the original metal, so the chemicals should be washed off soon after use. If the rust has only affected the surface, the appearance of the original metal can be restored. However, if the rust has deeply corroded the metal, then scars and pits will be left in the metal. The use of an oil or wax coating will help prevent future cases of rusting

Period 3 elements Featured 14 Sep 2004 Print

Period 3 elements

Period 3 elements. From left (in their periodic table order) they are: sodium (Na); magnesium (Mg); aluminium (Al); silicon (Si); phosphorus (P, white/red); sulphur (S); chlorine (Cl); and argon (Ar). Successive elements across the period, have a single electron added, and this causes immense changes in the chemical and physical properties. Metals (Na/Mg/Al) become non-metals (P/S/Cl/Ar), solids become gases, and reactive elements (Na/Mg) become inert (Ar). Mg is used in flares, Ar in light bulbs, and Si in microchips. P ands have different structural forms (allotropes). Cl and Ar form diatomic (Cl2) and monatomic (Ar) molecules
