Lintlha tsa motheo:
1. Foromo ea molek'hule: Se
2. Boima ba molek'hule: 78.96
3.Storage: Boloka sebakeng sa polokelo se pholileng, se nang le moea o pholileng le se omeletseng.Sireletsa ho tloha mongobo le ho pepeseha.
4.Packing: Sehlahisoa sena se lokela ho sebelisoa ka likhoeli tse tšeletseng, 'me ka kopo khutlisetsa li-remanins ka har'a sephutheloana sa vacuum.
Litlhaloso:
● Selenium ke ntho ea lik'hemik'hale e nang le letšoao la Se le nomoro ea athomo ea 34 'me e fumanoa e sa hloeka ka har'a tšepe ea sulfide.
● Selenium e na le li-isotopi tse tšeletseng tse hlahang ka tlhaho.Black Selenium ke ntho e thata e brittle, e benyang e qhibilihang hanyenyane ho CS2.
● E sebetsa ka ho khetheha ho hlahiseng selenium e hloekileng ka ho fetisisa e nang le likaroloana tse nyenyane ka ho fetisisa tsa boholo ba lijo-thollo.

Kopo:
1. Selenium e na le thepa e ntle ea photovoltaic le photoconductive, 'me e sebelisoa haholo ka lisebelisoa tsa elektronike, tse kang li-photocell, li-light meters le lisele tsa letsatsi.
2. Tšebeliso ea bobeli e kholo ka ho fetisisa ea selenium ke indasteri ea khalase: selenium e sebelisoa ho tlosa 'mala ho tloha khalase, ho fana ka' mala o mofubelu ho likhalase le li-enamel.
3. Tšebeliso ea metsotso ea boraro, ho nka hoo e ka bang 15% ke sodium selenite bakeng sa lijo tsa liphoofolo le lisebelisoa tsa lijo.
4. Selenium e ka boela ea fumana lits'ebetso ho fotokoping, ho toning ea lifoto.Tšebeliso ea eona ea bonono ke ho matlafatsa le ho atolosa mefuta e mengata ea litšoantšo tse ntšo le tse tšoeu.
5. Litšebeliso tse ling tsa selenium ke li-alloys tsa tšepe tse kang lipoleiti tsa loto tse sebelisoang ho boloka libeteri le li-rectifier ho fetola AC current ho DC current.
6. Selenium e sebelisetsoa ho ntlafatsa ho hanyetsa ha abrasion ka li-rubber tse nang le vulcanized.Metsoako e meng ea selenium e kenngoa ho li-shampoo tse thibelang letlalo.
