1. d-block Elements Transition Metals Most have high densities and high melting points. Usually strong, structurally useful materials. [http://www.colorado.edu/physics/2000/periodic_table/images/periodicTransMetal.jpg] Click here for videos on the Transition Metals

2. d-block Elements Many transition metals are made into alloys in order to combine their properties. Metals are melted then mixed together.

3. Steel is an alloy of carbon & iron.

4. The purity of gold is determined by the different ratios of gold, copper, and silver present.

5. d-block Elements Iron 4 th most abundant element in earth’s crust Easily rusts, so can be plated with Chromium to prevent this. [http://www.webelements.com/webelements/elements/media/element-pics/Fe.jpg] Click here for magnetism demo

6. d-block Elements “Coinage Metals” Copper, Silver, Gold Available pure in nature but rare… (25 th, 64 th, and 71 st respectively)

7. f-block Elements Inner Transition Metals 2 rows set apart from the periodic table. [http://www.bcpl.net/~kdrews/periodic%20chart/chart8.gif]

8. f-block Elements The rows are named after the 1 st element in each row, Lanthanum and Actinium [http://newark.rutgers.edu/~huskey/images/inner_metals.jpg]

9. f-block Elements Lanthanides widely distributed in nature but little commercial importance. Actinides are important because of radioactive properties (only Th & U are natural)
