Give some names of allotropic forms of group IV-A group elements
Answers
Answer:
The Parts of the Periodic Table - Angelo State University Group 4A (or IVA) of the periodic table includes the nonmetal carbon (C), the metalloids silicon (Si) and germanium (Ge), the metals tin (Sn) and lead (Pb), and the yet-unnamed artificially-produced element ununquadium (Uuq).
elements titanium (Ti) can transform into allotropic
Explanation:
1.Some chemical elements exist in two or more different forms, in the same physical state. These different forms are called allotropes.
2.Diamond, graphite and fullerene are different allotropes of carbon.Graphite is used in ribbons for printing in computes and typewriters and also in lead pencils.
3.Titanium undergoes an allotropic transformation at 882 °C.
4.Below this temperature, it exhibits a hexagonal close-packed (HCP) crystal structure, known as the α phase, while at a higher temperature, it has a body-centered cubic (BCC) structure, the β phase. The latter remains stable up to the melting point of 1,670 °C.
5.zirconium (Zr), chemical element, metal of Group 4 (IVb) of the periodic table, used as a structural material for nuclear reactors.
