鉭 (Ta)的波尔原子模型
Description
Rare, gray, heavy, hard but ductile, metal with a high melting point.
Uses
Often used as an economical substitute for platinum. Tantalum pentoxide is used in capacitors and in camera lenses to increase refracting power. It and its alloys are corrosion and wear resistant so it is used to make surgical and dental tools.
Sources
Chiefly occurs in the mineral tantalite. Always found with niobium.
Pronounciation (English)
TAN-te-lem
