Group 12 element - Wikipedia

Group 12, by modern IUPAC numbering, is a group of chemical elements in the periodic table.It includes zinc (Zn), cadmium (Cd) and mercury (Hg). The further inclusion of copernicium (Cn) in group 12 is supported by recent experiments on individual copernicium atoms. Formerly this group was named IIB (pronounced as "group two B", as the "II" is a Roman numeral) by CAS and old IUPAC system.

Dysprosium - Royal Society of Chemistry

Dysprosium's main use is in alloys for neodymium-based magnets. This is because it is resistant to demagnetisation at high temperatures. This property is important for magnets used in motors or generators. These magnets are used in wind turbines and electrical vehicles, so demand for dysprosium is growing rapidly.

ELEMENT: TITANIUM - RADIOCHEMISTRY SOCIETY

The metal can be purified by decomposing the iodide. Titanium, when pure, is a lustrous, white metal. It has a low density, good strength, is easily fabricated, and has excellent corrosion resistance. It is ductile only when it is free of oxygen. The metal, which burns in air, is the only element that burns in nitrogen.
