Lub cev muaj zog: Hauv av- lub xeev kev teeb tsa hluav taws xob ntawm bismuth atoms yog ib qho ntawm pawg nitrogen ntsiab lus, ns²np³. Nws qhov hnyav atomic (208.9804) muaj qhov tseeb tshaj plaws vim tsis muaj isotopic cuam tshuam. Bismuth muaj qhov loj tshaj plaws atomic thiab ionic radii hauv nws pawg, tab sis nws lub zog ionization thiab electronegativity zoo ib yam li antimony.
Nyob rau hauv chav tsev kub, nws yog xim hlau bismuth ( -bismuth) yog silvery -dawb nrog ib tug me ntsis rose-liab tint thiab ib tug txawv metallic luster . -bismuth (lub xeev hlau) qhia tib lub crystal qauv li -arsenic thiab antimony, nthuav tawm ib txheej txheej. Txhua bismuth atom nyob rau hauv nws cov txheej tsim ib daim duab peb sab pyramidal geometry nrog peb nyob ze atoms (r1), uas ua rau ib tug me ntsis undulating, wrinkled tsos. Tsis tas li ntawd, txhua bismuth atom tsim lwm daim duab peb sab nrog peb lub atoms nyob deb (r2) nyob rau hauv cov khaubncaws sab nraud povtseg. Lub interatomic nrug r1 thiab r2 maj mam nce raws li As -Sb-Bi txoj kev, tab sis r2/r1 piv txo qis zuj zus, qhia tias qhov sib txawv ntawm intra- thiab inter-txheej txheej kev sib cuam tshuam yog qhov tsis muaj zog, uas qhia txog qhov sib txawv ntawm kev ua hlau.
Nyob rau hauv siab dua, cov qauv siv lead ua ntawm bismuth tau hloov pauv zoo ib yam li cov antimony, pib ua ib qho yooj yim cubic lattice (Bi-Bi 318 pm); nrog rau kev nce ntxiv hauv siab, nws hloov mus rau hauv lub cev -centered cubic qauv, ntawm qhov taw tes Bi-Bi yog 329 teev tsaus ntuj.
