tantalum

 [tan´tah-lum]
a chemical element, atomic number 73, atomic weight 180.948, symbol Ta. (See Appendix 6.) It is a noncorrosive and malleable metal used for plates or disks to repair cranial defects, for wire sutures, and for making prosthetic appliances.

tan·ta·lum (Ta),

(tan'tă-lŭm),
A heavy metal of the vanadium group, atomic no. 73, atomic wt. 180.9479; used in surgical prostheses because of its noncorrosive properties.

tantalum

/tan·ta·lum/ (tan´tah-lum) chemical element, at. no. 73, symbol Ta; a noncorrosive and malleable metal that has been used for plates or disks to replace cranial defects, for wire sutures, and for making prosthetic appliances.

tantalum (Ta)

[tan′tələm]
Etymology: Gk, Tantalus, mythic king of Phrygia
a silvery metallic element. Its atomic number is 73; its atomic mass (weight) is 180.95. Relatively inert chemically, tantalum is used in prosthetic devices such as skull plates and wire sutures.
