A Group 6 element is one in the series of elements in group 6 (IUPAC style) in the periodic table, which consists of the transition metals chromium (Cr), molybdenum (Mo), tungsten (W), and seaborgium (Sg). In Chemistry a group, also known as a family, is a vertical column in the Periodic table of the Chemical elements There are 18 groups in In the Periodic table of the elements, a period is a horizontal row of the table A period 4 element is one of the Chemical elements in the fourth row (or period) of the periodic table of the elements. Chromium (ˈkroʊmiəm is a Chemical element which has the symbol Cr and Atomic number 24 A period 5 element is one of the Chemical elements in the fifth row (or period) of the periodic table of the elements. Molybdenum (məˈlɪbdənəm from the Greek word for the metal " Lead " is a Group 6 Chemical element with the symbol Mo A period 6 element is one of the Chemical elements in the sixth row (or period) of the periodic table of the elements, including the Lanthanides Tungsten (ˈtʌŋstən also known as wolfram (/ˈwʊlfrəm/ is a Chemical element that has the symbol W and Atomic number 74 A period 7 element is one of the Chemical elements in the seventh row (or period) of the periodic table of the elements. Seaborgium (siːˈbɔrgiəm is a Chemical element in the Periodic table that has the symbol Sg and Atomic number 106 Image of Seaborgium In Chemistry a group, also known as a family, is a vertical column in the Periodic table of the Chemical elements There are 18 groups in A chemical element is a type of Atom that is distinguished by its Atomic number; that is by the number of Protons in its nucleus. In Chemistry a group, also known as a family, is a vertical column in the Periodic table of the Chemical elements There are 18 groups in The International Union of Pure and Applied Chemistry ( IUPAC) (aɪjuːpæk or ay-yoo-pec) is an international Non-governmental organization The periodic table of the chemical elements is a tabular method of displaying the Chemical elements Although precursors to this table exist its invention is In Chemistry, the term transition metal (sometimes also called a transition element) has two possible meanings It commonly refers to any element in Chromium (ˈkroʊmiəm is a Chemical element which has the symbol Cr and Atomic number 24 Molybdenum (məˈlɪbdənəm from the Greek word for the metal " Lead " is a Group 6 Chemical element with the symbol Mo Tungsten (ˈtʌŋstən also known as wolfram (/ˈwʊlfrəm/ is a Chemical element that has the symbol W and Atomic number 74 Seaborgium (siːˈbɔrgiəm is a Chemical element in the Periodic table that has the symbol Sg and Atomic number 106 Image of Seaborgium
"Group 6" is the new IUPAC name for this group; the old style name was "group VIA" in the old European system or "group VIB" in the old US system. Group 6 must not be confused with the group with the old-style group names of either VIB (European system) or VIA (US system); that group is now called group 16.

Biological occurrences
Group 6 is notable in that it contains some of the only elements in periods 5 and 6 with a known role in the biological chemistry of living organisms: molybdenum is common in enzymes of many organisms, and tungsten has been identified in an analogous role in enzymes from some archaea, such as Pyrococcus furiosus. Enzymes are Biomolecules that catalyze ( ie increase the rates of Chemical reactions Almost all enzymes are Proteins Tungsten (ˈtʌŋstən also known as wolfram (/ˈwʊlfrəm/ is a Chemical element that has the symbol W and Atomic number 74 Pyrococcus furiosus is an extremophilic species of Archaea. It is notable for having an optimum growth temperature of 100°C (a temperature which would In contrast, and unusually for a first-row d-block transition metal, chromium appears to have few biological roles, although it is thought to form part of the glucose metabolism enzyme in some mammals. Glucose (Glc a Monosaccharide (or simple Sugar) also known as grape sugar, is an important Carbohydrate in Biology.

In Chemistry, the term transition metal (sometimes also called a transition element) has two possible meanings It commonly refers to any element in EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 In chemistry the Chemical elements labeled as synthetic are too unstable to be found naturally on Earth.
