Bromine nrog tus lej atomic ntawm 35 tau txais ib qho hluav taws xob kom ncav cuag 36 electrons. Qhov no ua rau nws isoelectronic nrog krypton.
Dab tsi ntxiv ions yog isoelectronic nrog KR?
Iodine, kuv, muaj 53 electrons, yog li kuv yuav muaj 54. Magnesium, Mg, muaj 12 electrons, yog li Mg2+ yuav muaj 10 electrons. Thaum kawg, strontium, Sr, muaj 38 electrons, uas txhais tau hais tias Sr2 + cation yuav muaj 36 electrons → isoelectronic nrog ib qho nruab nrab krypton atom.
Puas yog N3 isoelectronic nrog krypton?
Atoms thiab ions uas muaj tib lub teeb tsa hluav taws xobtau hais tias yog isoelectronic. Piv txwv ntawm hom isoelectronic yog N3–, O2–, F–, Ne, Na+, Mg2+, thiab Al3+ (1s22s22p6).
YPuas S2 isoelectronic nrog K+?
Ib txhia ntawm nws cov isoelectronic hom yog S2– ion (16 + 2=18 electrons), Cl– ion (17 + 1=18 electrons), K + ion (19 – 1=18 electrons), thiab Ca2 + ion (20 – 2=18 electrons).
YPuas isoelectronic nrog scandium?
Raws li tau hais lawm, ob tsis yog isoelectronicvim tias lawv cov qauv hluav taws xob sib txawv: potassium's ib qho hluav taws xob nyob rau hauv lub orbital thaum scandium (II)'s nyob hauv. ib d orbit. Qhov laj thawj ntawm qhov sib txawv no tsuas yog lwm qhov sib txawv: qhov sib txawv ntawm cov nqi hluav taws xob los ntawm 2.

Cov khub twg hauv qab no ntawm ions yog isoelectronic thiab isostructural?
Nrog rau qhov no peb yuav txiav txim siab tus naj npawb ntawm cov electrons hauv lub plhaub valence thiab nws cov qauv raws li txoj kev xav valence bond. Los ntawm cov lus piav qhia saum toj no peb tuaj yeem txiav txim siab tias khub ntawm isoelectronic thiab isostructural hom yog ClO−3, SO2−3.
Thaum twg yog hom isoelectronic?
Teb: Isoelectronic hom hu ua atoms lossis ions uas muaj tib tus lej ntawm electrons. Hauv hom isoelectronic, muaj pes tsawg tus electrons yuav sib npaug tab sis cov ntsiab lus yuav txawv. Hauv lwm lo lus, ions thiab atoms uas muaj cov lej sib npaug ntawm cov hluav taws xob hu ua hom isoelectronic.
Qhov txawv ntawm yam twg thiab yam twg?
"Txhua yam" yog siv los ua lub npe sib npaug rau " tsis muaj teeb meem dab tsi ". Nws yog ib feem tseem ceeb ntawm kab lus thiab tsis tuaj yeem muab tshem tawm. "Txhua yam" yog siv los ua ib qho adverb nrog kab lus nrog lub ntsiab lus tsis zoo.
Qhov twg hauv qab no yog qhov piv txwv ntawm qhov tsis suav nrog cov lej tsis suav nrog?
Pi is a non-terminating, non-repeating decimal. π=3.141 592 653 589 793 238 462 643 383 279 … e is a non-terminating, non-repeating decimal. Ib qho piv txwv ntawm tus lej tsis suav nrog yog dab tsi? Piv txwv: 0.5, 2.456, 123.456, thiab lwm yam.
