These are all transition metals in the d-block.All known isotopes of meitnerium are radioactive with short half-lives, and it is not known to occur in nature; only … The members of this group are: The group 14 elements have a general electronic configuration of ns 2 np 2. group 9 group of chemical elements. As cobalt - group of the periodic system, the elements of group 9 are referred to collectively in accordance with the IUPAC Nomenclature of inorganic. These elements have 2 electrons in the outermost p orbitals. There are 4 elements in group 9 in periodic table. From Academic Kids. The Group 7 elements are called the halogens. In modern IUPAC nomenclature, Group 9 of the periodic table contains the elements cobalt (Co), rhodium (Rh), iridium (Ir), and meitnerium (Mt). It is also called the carbon group. Group 9 element.
Before a name and symbol are approved, an element may be referred to by its atomic number (e.g., element 120) or by its systematic element name.

A group of elements on the periodic table is a vertical column. • The elements marked with an asterisk (in the 2nd column) have no stable nuclides. All known isotopes of Mt are radioactive with short half-lives, and it is not known to occur in nature; only minute quantities have been synthesized in laboratories. For example, element 120 has the temporary name unbinilium.
