h\u0207lij <\/span>helij<\/span> im. m.<\/span> (G h\u0207lija, DL h\u0207liju, A h\u0207lij, I h\u0207lijem<\/span>)<\/span><\/span><\/span><\/p>\n

kem.<\/span> Helij je kemijski element (He), bezbojni plemeniti plin bez okusa i mirisa, najlak\u0161i od plinova, u ve\u0107im ga koli\u010dinama ima na Suncu i na nekim zvijezdama, upotrebljava se za punjenje zra\u010dnih balona.<\/span><\/span> <\/span><\/span><\/p>\n

– Na pro\u0161loj akciji odr\u017eanoj 2010 godine, nazvanoj Plu\u0107a grada<\/span> prolaznici su pisali poruke na balone napunjene helijem koji su zatim pu\u0161tani u nebo.<\/span><\/p>\n

<\/p>\n

– U slu\u010daju levitiraju\u0107ih vlakova trenja nema, pa se vlakovi gibaju br\u017ee i s manje gubitaka, a nezgodno je jedino to \u0161to se pritom koriste supravodi\u010di hla\u0111eni teku\u0107im helijem, pa su takvi vlakovi jako skupi te ih zbog toga malo ima. <\/span><\/p>\n

<\/p>\n

– Jezgre dvaju izotopa vodika, deuterija i tricija, spajaju se u jezgru helija.<\/span><\/p>\n

<\/p>\n

Kakav je helij?<\/span> superfluidni, suprafluidni, teku\u0107i<\/span><\/span><\/p>\n

\u0160to se s helijem mo\u017ee?<\/span> napuniti (balon)<\/span><\/span><\/p>\n

Koordinacija;<\/span> du\u0161ik i helij, helij i argon, helij i kisik, vodik i helij<\/span><\/span><\/p>\n

U vezi s helijem spominje se:<\/span> atom, balon, boca, izotop, fuzija, jezgra, masa, spremnik<\/span><\/span><\/p>\n

<\/p>\n

tvorenice: helijev<\/span><\/p>\n
