Stefan V. The electron configuration ntawm qhov nruab nrab sodium atom yog 1s22p63s1. Hauv no kev teeb tsa peb nco ntsoov tias tsuas muaj ib leeg xwb hluav taws xob hauv qib 3 lub zog. Atoms nyiam kom tau txais kev ruaj ntseg ntawm octet, los ntawm muaj yim electrons hauv lub plhaub sab nraud, lub electrons ntawm s thiab p orbitals.
Nyob rau hauv tas li ntawd, dab tsi yog qhov electron configuration ntawm sodium ion?
[Ne] 3s¹
Tsis tas li ntawd, ns2np6 txhais li cas? Noble gas configuration yog lub sij hawm muab rau electron configuration ntawm noble gases. Lub hauv paus ntawm tag nrho cov tshuaj tiv thaiv yog qhov nyiam ntawm cov tshuaj lom neeg kom tau txais kev ruaj ntseg. Tag nrho cov noble gases tshwj tsis yog helium muaj kev ruaj ntseg dav dav hauv hluav taws xob hauv lub plhaub valence uas ns2np 6.
Ib yam li ntawd ib tug yuav nug, dab tsi yog lub hauv paus xeev hluav taws xob configuration ntawm sodium ion Na +?
Feem ntau ions feem ntau yog cov uas tau txais lossis poob electrons kom tau txais lub plhaub kaw. Piv txwv: Na muaj ib hauv av - xeev electronic configuration ib 1s2 2s2 2p6 3s1. Tshem tawm 3s hluav taws xob tawm peb nrog cov roj noble kev teeb tsa 1s2 2s2 2p6, ua a sodium ion yog Na+.
Muaj pes tsawg electrons nyob hauv Na +?
Ib qho Na + ion yog sodium atom uas tau poob ib qho hluav taws xob uas ua rau cov xov tooj hluav taws xob hauv lub atom sib npaug rau qhov ze tshaj plaws Nobel roj Neon uas muaj 10 electrons . Qhov no tag nrho ua rau 1st thiab 2nd electron plhaub. Sodium atom muaj 11 protons, 11 electrons thiab 12 neutron.

Element General sab nrauv hluav taws xob configuration p–block(metals & non metals) ns2np1–6, where n = 2 – 6 d–block(transition elements) (n–1) d1–10 ns0–2, where n = 4 – 7 f -block(internal transition elements) (n–2)f1–14(n–1)d0–10ns2, where n=6–7
Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
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
