d-block Elements Transition Metals Most have high densities and high melting points. Usually strong, structurally useful materials. [ Click here for videos on the Transition Metals

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

Steel is an alloy of carbon & iron.

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

d-block Elements Iron 4 th most abundant element in earth’s crust Easily rusts, so can be plated with Chromium to prevent this. [ Click here for magnetism demo

f-block Elements Inner Transition Metals 2 rows set apart from the periodic table. [

f-block Elements The rows are named after the 1 st element in each row, Lanthanum and Actinium [

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