Overview<\/h3>\n

The transition metals occupy a large area on the periodic table.\u00a0 They all appear to have similar metallic properties, because of the way their electron shells are filled. \u00a0\u00a0Many transition metals form brightly colored compounds, especially in solution.\u00a0 The transition metal group includes common elements such as iron (Fe), copper (Cu), nickel (Ni), gold (Au), and silver (Ag).<\/p>\n

The Periodic Table and Transition Metals<\/h3>\n

Transition metals are also called transition elements.\u00a0 They are in Groups 3B through 2B, or 3 -12 of the periodic table, occupying the space between the alkali earth metals on the left and the true metals on the right.\u00a0 They are a very large group of 38 elements.\u00a0 Also, chemists usually consider the elements in the lanthanide and actinide series as inner transition elements.\u00a0 There are so many of them that they are usually in a special configuration under the main periodic table.<\/p>\n

Properties of Transition Metals<\/h3>\n

Transition metals are usually solids (except for mercury which is liquid at room temperature), often with high melting and boiling points.\u00a0 They are shiny, metallic, dense, and are often excellent conductors of both heat and electricity.\u00a0 Some transition metals, such as gold and platinum, do not react easily with oxygen, so they resist oxidation, while iron, another transition metal, rusts easily.\u00a0 Technically, transition metals are in the d-block of the periodic table.<\/p>\n

\"\"<\/a><\/p>\n

Compounds<\/h3>\n

By definition, transition metals form various types of compounds by giving up different numbers of electrons from their incomplete d shells.\u00a0 For example, sometimes iron gives up 2 electrons and sometimes it gives up 3 when it is oxidized.\u00a0 Trace amounts of transition metals in compounds color paint pigments.\u00a0 Traces of iron color citrine yellow and jade green, and traces of chromium color rubies red.\u00a0 Some of the most unusual colors are caused when transition metals are dissolved in liquid (aqueous) solution.<\/p>\n

Types of Transition Metals<\/h3>\n

The 38 elements include some of the most well-known metals.\u00a0 For example, iron (Fe) is the fourth most abundant element in the Earth\u2019s crust and one of the most widely used in manufacturing.\u00a0 Since pure iron is a soft metal, it is usually alloyed with other elements to make it harder, often as steel.\u00a0 Iron is also essential to life, as it is contained in hemoglobin for vertebrates and in plant cells.\u00a0 Copper (Cu) is used in electrical wiring, as it is one of the best conductors, in alloys such as bronze, and even in copper pipes.\u00a0 Nickel (Ni) is used in alloys, especially with iron, in coins, and is essential to life in some enzymes.\u00a0 The transition metals are also excellent catalysts.<\/p>\n
