Cov ntsiab lus boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium polonium Polonium yog cov khoom siv hluav taws xob uas muaj nyob hauv ob lub hlau alloys.. Daim ntawv alpha yog tib qho piv txwv ntawm qhov yooj yim cubic crystalqauv hauv ib qho atom hauv paus ntawm STP, nrog ntug ntev ntawm 335.2 picometers; daim ntawv beta yog rhombohedral. https://en.wikipedia.org › wiki › Polonium

(Po) thiab astatine (At) yog xav txog metalloids. Metalloids ua cov cua sov thiab hluav taws xob nruab nrab ntawm cov hlau tsis muaj hlau thiab hlau thiab lawv feem ntau tsim oxides.
Puas yog astatine yog metalloid lossis halogen?
Dab tsi ntxiv, raws li Kozimor taw qhia, astatine tiv thaiv kev faib tshuaj yooj yim. Thaum nws zaum hauv kem ntawm halogen ntsiabntawm lub rooj zaum, nws kuj nyob ntawm kab kab pheeb ces kaum uas muaj cov metalloids xws li boron thiab silicon. Hauv kev cuam tshuam, qee zaum nws ua zoo li halogen, qee zaum zoo li hlau.
Puas yog astatine yog nonmetal?
Raws li Elemental Matter, halogen cov ntsiab lus, suav nrog astatine, faib cov khoom zoo sib xws; lawv yog cov hlau tsis yog hlau, muaj cov ntsiab lus melting tsawg thiab boiling, nkig thaum khoom, tsis zoo conductors ntawm tshav kub thiab hluav taws xob, thiab yog diatomic (lawv cov molecules muaj ob atoms).
Puas yog astatine ib yam khoom?
Astatine yog muaj xov tooj cua muaj zog heev thiab nws yog qhov hnyav tshaj plaws paubhalogen. Nws cov khoom siv tshuaj yog ntseeg tau zoo ib yam li cov iodine. Puas tau tshawb fawb me ntsis vim tias tag nrho nws cov isotopes muaj luv luv ib nrab neej.
Dab tsi yog cov khoom tsis tshua muaj nyob hauv lub qab ntuj khwb?
Astatine yog qhov tshwm sim tsis tshua muaj tshwm sim.
