Tantalum-181 Information

Tantalum is a hard blue-grey metallic transition element. Totally there are 36 isotopes of tantalum. It has 2 natural isotopes - Ta-181 and Ta-180m. Ta-181 is a stable isotope, and Ta-180m is a stable isomer and it is the only naturally occurring one. Tantalum is used in surgery as it is unreactive. This element forms a protective oxide layer in air. Tantalum was identified by Ekeberg in 1802 and was isolated by Jons J. Berzelius in 1820.

Tantalum is used often 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.
