Corrosion of Metals Introduction Have you ever had a bike that went rusty‚ figure 1? If the paint is scratched and the rust allowed to spread‚ it is very difficult to repair the frame so it looks as good as new again. Rusting costs us millions of pounds each year‚ either through replacing things or through trying to prevent it happening in the first place. Figure 1: Bike rusting. In this booklet you learn about rusting and ways of stopping it‚ followed by a look at another metal‚ aluminium that

Tony Nguyen Honors Chemistry Period 7 9/17/13 The Density of Metals Lab BACKROUND: Density is a constant relationship between the mass and volume of a specific type of matter. Measurements of both mass and volume can be obtained for a metal sample. The relationship can be shown graphically by plotting the volume of a sample on the horizontal x-axis and the mass of the sample along the vertical y-axis. Plotting the values for several samples‚ a linear relationship can be seen for a density (slope=density)

Extraction of metals The History of Metals. Metals have been used by people for many thousands of years. Gold and silver‚ found as native metal‚ were used both as jewellery and as a status symbol - nothing new there. These metals were known in the Stone Age‚ but gold and silver are too soft to be used as tools. The first really useful metal to be discovered was bronze. This began the Bronze Age. Bronze was used extensively for tools and weapons in Asia and Africa from 4‚500 B.C. (6‚500 years

Transition Metals 1a) The d-orbitals of a free transition metal atom or ion are degenerate (all have the same energy.) However‚ when transition metals form coordination complexes‚ the d-orbitals of the metal interact with the electron cloud of the ligands in such a manner that the d-orbitals become non-degenerate (not all having the same energy.) The way in which the orbitals are split into different energy levels is dependent on the geometry of the complex. Crystal field theory can be used to predict
