Transition Metals

The 38 elements of Groups 3 to 12 of the Periodic Table of the Elements are called "transition metals". As with all metals, transition elements are both ductile and malleable, electrical and thermal. An interesting point of transition metals is that their valence electrons or electrons used to bind them to other elements are present in multiple shells. This is why they often show some common oxidation state. There are three noteworthy elements in the transition metal series. These elements are iron, cobalt and nickel, which are the only elements known to generate magnetic fields.

Gallium is a late transition metal. These are metal elements between the transition metal and semimetal (nonmetal) of the periodic table. Post-transition metals have some properties of transition metals, but tend to be softer and worse results. Post transition metals include several boron elements - aluminum, indium and antimony - and tin (Sn), lead (Pb) and antimony (Bi). Gallium has several very unique properties. For example, it is solid at room temperature (about 77 F / 22 C) but still very soft, so you can cut it with a knife. In addition, it has a low melting point (10 degrees below room temperature) of 85.57 degrees Fahrenheit (29.76 degrees Celsius), so if gallium is taken in hand it melts from the warmth of your hands. When it is restored, it will set again

Transition metals are also very useful for their magnetic properties. Some transition metals form paramagnetic compounds which are subject to magnetic fields. Others form diamagnetic compounds instead. In view of this versatility, transition metals can be used to create materials that are intentionally or not sensitive to magnetic fields. In addition, certain transition metals - iron, cobalt and nickel - can be used to prepare ferromagnetic solids. A ferromagnetic solid is a solid that generates a magnetic field. For example, a strip magnet is ferromagnetic
