Elementos do Grupo 4. O grupo 4 ( 4B) da tabela periódica é conhecido como “Grupo do Titânio”. É constituído dos elementos: [ 1] Titânio ( 22 Ti); Zircônio ( 40 Zr); Háfnio ( 72 Hf); Rutherfórdio ( 104 Rf) ( sintético ).
The Roman numerals used correspond to the last digit of today's naming convention (e.g. the group 4 elements were group IVB, and the group 14 elements were group IVA). In Europe, the lettering was similar, except that "A" was used for groups 1 through 7, and "B" was used for groups 11 through 17.
Group 4 is a group of elements in the periodic table. It contains the elements titanium, zirconium, hafnium and rutherfordium. This group lies in the d-block of the periodic table.
The chemistry of the group 4 metals is dominated by the +4 oxidation state. Only Ti has an extensive chemistry in lower oxidation states. In contrast to the elements of group 3, the group 4 elements have important applications.
