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.
