Potassium yog cov khoom siv tshuaj nrog lub cim K thiab tus lej atomic 19. Potassium yog cov hlau dawb-dawb uas yog mos txaus los txiav nrog rab riam nrog lub zog me me. Potassium hlau reacts sai nrog atmospheric oxygen los tsim flaky dawb poov tshuaj peroxide hauv vib nas this ntawm raug.
Koj sau li cas cov khoom siv hluav taws xob rau cov poov tshuaj?
Yog li ntawd cov Potassium electron configuration yuav yog 1s22s22p 6 3s23p64s1 Cov kev teeb tsa ua kom yooj yim txoj hauv kev rau cov kws tshawb fawb los sau thiab sib txuas lus li cas electrons tau teem ib ncig ntawm lub nucleus ntawm ib lub atom.
Vim li cas electron configuration ntawm poov tshuaj?
Raws li txoj cai octet, lub plhaub sab nraud ntawm ib lub atom tuaj yeem ua tau ntau tshaj 8 electrons (tshwj tsis yog K plhaub uas tuaj yeem ua tau siab tshaj 2 electrons). Yog li ntawd, qhov kev teeb tsa hluav taws xob ntawm cov poov tshuaj yog 2, 8, 8, 1 thiab tsis yog 2, 8, 9.
Vim li cas kab thib 2 ntawm lub rooj zaum muaj 8 lub ntsiab?
Lub plhaub thib ob muaj ob lub plhaub 2s thiab 2p uas muaj tag nrho plaub lub orbitals li no yim electrons tuaj yeem ua tiav hauv plaub lub orbitals thiab yog li lub sijhawm thib ob muaj yim yam.
Qhov twg ruaj khov dua K lossis K + Vim li cas?
Atomic naj npawb ntawm k=19, … Peb pom tias, Pottasium (k) muaj 1 electron nyob rau hauv nws lub plhaub sab nraud, Yog li k +yuav muaj, 8 qhov hluav taws xob sab nraud, Raws li Txoj cai Octet, K+ yuav ruaj khov dua !.
