Tantalum (Tantalum) ke ntho ea tšepe e nang le nomoro ea athomo ea 73, a
letšoao la lik'hemik'hale Ta, ntlha e qhibilihang ea 2996 ° C, ntlha e belang ea 5425 ° C,
le boima ba 16.6 g/cm³. The element e tsamaellanang le element ke
metal grey metal, e nang le khanyetso e phahameng haholo ea kutu. Ha ho joalo
itšoara joang ho hydrochloric acid, concentrated nitric acid le aqua regia ho sa tsotellehe
tlasa maemo a batang kapa a chesang.
Tantalum e fumaneha haholo ho tantalite mme e kopana le niobium. Tantalum ke
e thata ka mokhoa o itekanetseng, 'me e ka huloa ka likhoele tse tšesaane ho etsa
li-foil tse tšesaane. Coefficient ea eona ea katoloso ea mocheso e nyane. Tantalum e monate haholo
thepa e ntle ea lik'hemik'hale 'me e hanyetsana haholo le ho bola. Ho ka ba joalo
e sebelisetsoang ho etsa likepe tsa mouoane, joalo-joalo, hape e ka sebelisoa e le li-electrode,
li-rectifiers, le li-capacitor tsa electrolytic tsa li-elektronike tubes. Ka bongaka, e sebelisoa ho
etsa dishiti kapa likhoele tse tshesane ho lokisa dinama tse senyehileng. Le hoja tantalum e
e hanyetsa haholo ho senya, ho hanyetsa ha eona ho bakoa ke ho thehoa
ea filimi e tsitsitseng e sireletsang ea tantalum pentoxide (Ta2O5) holim'a metsi.
