Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Technetium isimbi yesirivha-grey ine mwaranzi nechitarisiko chakafanana neplatinum, inowanwanwanwa seupfu hwakasviba. Chimiro chekristaro chesimbi yakachena chine mativi matanhatu akavharwa. Atomic technetium ine hunhu hwemitsetse yekuburitsa pane aya mafungu marefu echiedza: 363.3 nm, 403.1 nm, 426.2 nm, 429.7 nm, uye 485.3 nm. Chimiro chesimbi chiri paramagnetic zvishoma, zvichireva kuti magnetic dipoles ayo anoenderana neminda yemagineti yekunze, asi anozofungidzira mafambiro asina kujairika kana munda wabviswa. Technetium yakachena, yesimbi, yekristaro imwe chete inova mhando-II superconductor patembiricha iri pasi pe7.46 K. Pasi peichi tembiricha, technetium ine yakadzika kwazvo yekupinda kwemagineti, yakakura kupfuura chero chimwe chinhu kunze kweiyoobium.  Mubvunzo: Technetium ine ruvara rwakaita sei?
