Seminole Group - Hafnium

Hafnium and Nuclear Power just like Zirconium!

Hafnium is a tetravalent chemical element that has four electrons in its valence (outermost) shell that are available for covalent bonding. Hafnium became the second to last element with stable isotopes to be discovered. It is found in zirconium, resembles zirconium, and the two minerals are the two most difficult to separate.

Hafnium is silver-gray, lustrous and resistant to corrosion. The main uses of hafnium are complementary to zirconium in nuclear power plants. It is also used in filaments and electrodes and in integrated circuits as a gate insulator for transistors.
