Ib atom uas tau txais a tsis zoo electron , nws ua a tsis zoo ion. Yog nws poob ib tug electron nws ua ib tug zoo ion. Nws tuaj yeem poob ib qho ntawm nws electrons , ua kom muaj ion. Nws tam sim no muaj ntau qhov zoo protons dua electrons yog li nws muaj tag nrho cov nqi zoo.
Yog li ntawd, vim li cas lub atom uas tau txais ib qho hluav taws xob ua tsis zoo?
Ib txhia atoms muaj ze yim electrons nyob rau hauv lawv lub plhaub valence thiab tuaj yeem nce ntxiv valence electrons mus txog thaum lawv muaj octet. Thaum cov no atoms nce electrons , lawv tau a tus nqi tsis zoo vim tam sim no lawv muaj ntau dua electrons tshaj protons. Negatively them ions hu ua anions.
Tsis tas li ntawd, yuav ua li cas tshwm sim thaum lub chlorine atom tau txais ib qho hluav taws xob nws hu ua dab tsi? Muaj 18 electrons thiab 17 protons, yog li cov tshuaj chlorine atom tau ua tus nqi them tshuaj chlorine ion nrog tus nqi ntawm qhov tsis zoo (-1). Thaum nws siv rau qhov ntxiv hluav taws xob , ua a tshuaj chlorine ion, nrog tus nqi ntawm qhov tsis zoo (-1).
Tsis tas li ntawd, thaum lub atom tau txais ib qho hluav taws xob nws puas ua anion?
Yog atoms poob electrons , lawv ua zoo ions, los yog cations. Yog atoms nce electrons , lawv ua negative ions, los yog anions . Xav txog qhov piv txwv ntawm fluorine (saib daim duab hauv qab). Ib fluorine atom muaj cuaj protons thiab cuaj electrons , yog li nws yog hluav taws xob nruab nrab.
Dab tsi yog qhov tsis zoo them atom hu ua?
Negatively them los yog zoo them atom feem ntau hu ua ANION/CATION. Kev piav qhia luv luv: Yog tias ib qho atom poob electrons lossis nce protons, nws yuav muaj qhov zoo nqi thiab yog hu ua ib Cation. Yog ib atom nce electrons los yog poob protons, nws yuav muaj net tus nqi tsis zoo thiab yog hu ua ib Anion.

Vim li cas kuv lub tshuab hluav taws xob tsis tsim hluav taws xob?
Feem ntau ua rau lub tshuab hluav taws xob portable tsis tsim hluav taws xob yog los ntawm kev poob ntawm cov hlau nplaum seem. Generators ua hauj lwm los ntawm kev txav hluav taws xob conductors los ntawm magnetic teb. Koj lub tshuab hluav taws xob tsis muaj hlau nplaum. Thaum cov hlau nplaum seem ploj lawm, lub tshuab hluav taws xob yuav tsis muaj zog thaum pib
Vim li cas cov hluav taws xob sab nraud tsuas yog suav nrog hauv daim duab kos duab hluav taws xob?
Atoms nrog 5 los yog ntau tshaj valence electrons tau electrons tsim ib tug tsis zoo ion, los yog anion. Vim li cas thiaj li cov hluav taws xob sab nraud tsuas yog cov uas suav nrog hauv daim duab orbital filling? lawv tsuas yog cov uas koom nrog cov tshuaj tiv thaiv thiab kev sib raug zoo. 2s orbital nyob deb ntawm lub nucleus txhais tau tias nws muaj zog ntau dua
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Dab tsi yog qhov zoo ntawm kev siv lub tshuab hluav taws xob hloov hluav taws xob hauv atomic absorption?
Qhia qhov zoo thiab qhov tsis zoo ntawm lub cub tawg piv nrog kev siv cov nplaim taws hauv atomic absorption spectroscopy. Cov txiaj ntsig tseem ceeb yog ntau dua rhiab heev (concentration thiab tshwj xeeb tshaj yog loj). Lub ntsiab tsis zoo yog cov cuab yeej cuab tam ntau dua thiab cov nqi ntsuas
