A Group 8 element is one in the series of elements in group 8 (IUPAC style) in the periodic table, which consists of the transition metals iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs). 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. Iron (ˈаɪɚn is a Chemical element with the symbol Fe (ferrum and Atomic number 26 A period 5 element is one of the Chemical elements in the fifth row (or period) of the periodic table of the elements. Ruthenium (ruːˈθiːniəm is a Chemical element that has the symbol Ru and Atomic number 44 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 Osmium (ˈɒzmiəm is a Chemical element that has the symbol Os and Atomic number 76 A period 7 element is one of the Chemical elements in the seventh row (or period) of the periodic table of the elements. Hassium (ˈhæsiəm or /ˈhɑːsiəm/ is a Synthetic element in the Periodic table that has the symbol Hs and Atomic number 108 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 Iron (ˈаɪɚn is a Chemical element with the symbol Fe (ferrum and Atomic number 26 Ruthenium (ruːˈθiːniəm is a Chemical element that has the symbol Ru and Atomic number 44 Osmium (ˈɒzmiəm is a Chemical element that has the symbol Os and Atomic number 76 Hassium (ˈhæsiəm or /ˈhɑːsiəm/ is a Synthetic element in the Periodic table that has the symbol Hs and Atomic number 108
All of these elements are classed in Group 8 because their valence shells hold eight electrons. An electron shell may be crudely thought of as an Orbit followed by Electrons around an Atom nucleus. Hassium can only be produced in the laboratory and has not been found in nature.
