Transcript of Transition Metals

By: Katie Scaglione, Nicole Sileo, and Lauren Scaglione Sources Compound and Reactions Transition Metals come from deposits in the Earth's crust. Minerals that are used for the commercial production of metals are called ores. Uses: Nickel, iron, titanium, and copper are used in electrical technology and in the construction of buildings. Transition Metals An increase in the atomic number of an element results in an increase of the number of electrons in the 2nd highest occupied energy level.
In periods 5 and 6 of the period table, transition metals in the same group have very similar, if not exact, atomic radii. These also have similar atomic properties and occur together in nature. Good Conductors of heat and electric current Density and melting point increase to a peak in row 6B then decrease from there Ductile, or flexible without loss of toughness Malleable, or able to be pressed or hammered
permanently out of shape Compound of these transition metals tend to have a distinctive color Transition metals are the only elements that can produce a magnetic field. All transition metals are metallic and have high electrical conductivity. There is only one liquid transition metal at room temperature. It is Mercury (Hg). All the others elements in the transition metals are solid. Many transition metals, such as gold, are alloys. Alloys are metals made by combining two or more metallic elements, especially to give greater strength or resistance to corrosion. Group 1A and 2A metals are easily oxidized on exposure to air Transition Metals are located in the "d" block when finding the electron configuration. Therefore, the electron configurations end with either 3d, 4d, 5d, or 6d. They also react with water to release hydrogen Compounds formed with Transition metals tend to have a distinctive color Physical Properties Atomic Properties Other Facts The End! For centuries, people have developed techniques for separating metals from ores. The ore is concentrated and the metal is removed by reduction. Then, the metal is refined and purified. Some transition metals, like gold and silver are found uncombined in nature, while other transition metals are found combined with another element. For example, Iron is found combined with oxygen. Transitions Metals Most transition metals have 2 valence electrons. These colors are usually caused from either charge transfer, when and electron jumps orbitals, and in d-d transitions, where the electron jumps from one D orbital to the other. These metals are also unique because they have an incomplete shell
