This transition metal is found in about 65 minerals, phosphate rocks, some iron ores and crude oils, etc. Its has oxidation states that appear in a wide range of beautiful colors, which is why its name was derived from Vanadis, the Norse goddess of beauty. uses: Alloyed with steel for its toughness, shock resistance, and its low neutron-absorbing properties useful for nuclear reactors. Its pentoxide compound is used as a catalyst to produce sulfuric acid. What is this element, its symbol, its atomic number, and its atomic mass?

Zinc, Zn, 30, 65.380

This transition metal is known for its gold-colored alloy with copper, brass. Its primary ore is sphalerite. It is bluish gray in its natural state, slightly brittle, and has a relatively low melting point. Its name was taken from the same German word. uses: Used as a coating in galvanized metals. Its sulfide comp is used in luminous paints, fluorescent lights, and x-ray screens. Essential to life, it forms many enzymes. Used as the anode in alkaline batteries. What is this element, its symbol, its atomic number, and its atomic mass?

Yttrium, Y, 39, 88.906

This transition metal is one of the rare earth elements along with scandium and the lanthanides. It's a component of the synthetic crystal YAG, which is used in capsulotomy. This and four other elements were named after the Swedish village, Ytterby. uses: Added to Al & Mg alloys for strengthening. YBCO is a superconductor at ~92 K. Y2O3 is added to the glass of camera lenses to make it heat, shock resistant and is used to make phosphors that impart red color. What is this element, its symbol, its atomic number, and its atomic mass?

Manganese, Mn, 25, 54.938

This transition metal is the 5th most abundant metal in the Earth's crust. Some of its widely distributed minerals are pyrolusite and rhodochrosite. Its name was derived from either Latin "magnes", meaning magnet, or "magnesium nigra", black magnesium oxide. uses: Alloyed with steel to make it stronger for use in railway tracks, safes, prison bars, etc. Alloyed w/Al for its corrosion resistance. Used as a catalyst to make plastic bottles. Essential to the process of photosystem II. What is this element, its symbol, its atomic number, and its atomic mass?

Chromium, Cr, 24, 51.996

This transition metal is the hardest metal according to the Mohs scale. It is highly resistant to corrosion, which is why it's alloyed with many other metals. It's named after the Greek word "chroma", meaning "color", because of its colorful compounds. uses: Alloyed with steel to make stainless steel. Used as plating to give a polished mirror finish to objects such as metals or plastics. Its compounds are used as pigments. Used in medicines effective for diabetes. What is this element, its symbol, its atomic number, and its atomic mass?

Technetium, Tc, 43, [98]

This transition metal is the lightest element that has all of its isotopes being radioactive. It was predicted by Mendeleev as the "ekamanganese" and was later artificially made in 1937. Its name was derived from the Greek word "tekhnetos", meaning artificial. uses: The gamma-ray emitting 99m isotope is widely used in nuclear medicine. Through its relatively short half-life, its detection in stars helped prove that stars can produce heavier elements. What is this element, its symbol, its atomic number, and its atomic mass?

Iron, Fe, 26, 55.845

This transition metal is the most abundant element on Earth (most are found in the core). It's the main component of a very essential alloy, steel. Its name was derived from the same Anglo-Saxon term, while its symbol came from its Latin name "ferrum". uses: Steel is the most important industrial alloy. Creates the Earth's magnetic field. It's in the center of the heme in hemoglobin. Participates in the highly exothermic thermite reaction used in welding railroad tracks. What is this element, its symbol, its atomic number, and its atomic mass?

Nickel, Ni, 28, 58.693

This transition metal is very resistant to corrosion even at high temperatures. It has a history of being used in coins, and it gives a green color to glass when added. It's named after the German word "kupfernickel", meaning St. Nicholas's copper. uses: Its many alloys are used in systems that operate in high temps such as toasters, desalination plants, turbine blades, etc. Used to plate other metals for protection. Used in rechargeable NiMH batteries. What is this element, its symbol, its atomic number, and its atomic mass?
