Group 4 Element
The Group 4 elements are a group of chemical elements in the periodic table. In the modern IUPAC nomenclature, Group 4 of the periodic table contains titanium (Ti), zirconium (Zr), hafnium (Hf) and rutherfordium (Rf). This group lies in the d-block of the periodic table. The group itself has not acquired a trivial name; it belongs to the broader grouping of the transition metals.
The three Group 4 elements that occur naturally are titanium (Ti), zirconium (Zr) and hafnium (Hf). The first three members of the group share similar properties; all three are hard refractory metals under standard conditions. However, the fourth element rutherfordium (Rf), has been synthesized in the laboratory; none of its isotopes have been found occurring in nature. All isotopes of rutherfordium are radioactive. So far, no experiments in a supercollider have been conducted to synthesize the next member of the group, unpenthexium (Uph), and it is unlikely that they will be synthesized in the near future.

Famous quotes containing the words group and/or element:
“Its important to remember that feminism is no longer a group of organizations or leaders. Its the expectations that parents have for their daughters, and their sons, too. Its the way we talk about and treat one another. Its who makes the money and who makes the compromises and who makes the dinner. Its a state of mind. Its the way we live now.”
—Anna Quindlen (20th century)
“To get a man soundly saved it is not enough to put on him a pair of new breeches, to give him regular work, or even to give him a University education. These things are all outside a man, and if the inside remains unchanged you have wasted your labour. You must in some way or other graft upon the mans nature a new nature, which has in it the element of the Divine.”
—William Booth (18291912)
