Electron - Ib qho subatomic particle uas muaj qhov tsis zoo
Hlau - Ib keeb uas yog ci iab thiab ua cua sov thiab hluav taws xob zoo.
Ua li no, yam khoom twg ci ntsa iab thiab tsis ua hluav taws xob?
Lub npe yog tias cov khoom no yog a hlau , nonmetal, los yog metalloid: Ib yam khoom yog nkig, ci, tsis hnov mob nrog acid, thiab tsis ua hluav taws xob. Nonmetal (nkig, tsis hnov mob nrog cov kua qaub, thiab tsis ua hluav taws xob yog qhov tseem ceeb ntawm nonmetal).
Ib tug kuj yuav nug, pab pawg twg ntawm lub rooj noj mov muaj cov tshuaj uas ci ntsa iab thiab ua hluav taws xob? Alkaline hlau feem ntau yog ci iab khov uas kev coj cua sov los yog hluav taws xob thiab tuaj yeem tsim ua cov ntawv. Transition metals yog cov cov ntsiab lus nyob nruab nrab ntawm cov daim ntawv qhia hnub . Cov no cov ntsiab lus , cais raws li "kev hloov pauv hlau", tuaj yeem pom hauv pab pawg 3 mus rau 12 lub hlis daim ntawv qhia hnub.
Hais txog qhov no, lub ntsiab lus twg yog qhov tsis zoo ntawm cov cua sov?
Lead yog cov neeg ua haujlwm tsis zoo tshaj plaws ntawm cov cua sov. Bismuth, mercury thiab hlau kuj yog cov conductors tsis zoo.
Lub ntsiab lus twg yog khoom nyob rau hauv chav tsev kub thiab ib tug zoo conductor ntawm tshav kub thiab hluav taws xob?
8th Qib Science Unit 5. Ch. 15 Lub Sijhawm Teev Taw. Glencoe/McGraw-Hill. Xyoo 2005.

Hlau. | cov khoom uas muaj luster, yog malleable, ductile, thiab ib tug zoo conductor ntawm tshav kub thiab hluav taws xob. |
Nonmetals. | cov khoom uas feem ntau yog cov roj los yog cov khoom tawg ntawm chav tsev kub thiab yog ib qho tsis zoo ntawm cov cua sov thiab hluav taws xob. |

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 txawv ntawm tus kws tshaj lij hluav taws xob thiab tus kws tshaj lij hluav taws xob?
Qhov sib txawv tseem ceeb ntawm cov kws tshaj lij hluav taws xob thiab cov kws tshaj lij xov tooj cua yog lawv cov qib kev kawm.Lawv yuav tau dhau ob qho kev xeem ntawv pov thawj RN thiab theradiology cov kws saib xyuas neeg mob daim ntawv pov thawj xws li ib tus tswj hwm los ntawm Lub Koom Haum rau Radiologic & ImagingNursing
Kev sib raug zoo ntawm hluav taws xob thiab hluav taws xob teb yog dab tsi?
Electric teb yog txhais raws li lub zog hluav taws xob ib chav tsev nqi. Cov kev taw qhia ntawm lub teb yog coj mus rau qhov kev taw qhia ntawm lub zog nws yuav ua rau ib tug zoo kuaj nqi. Cov hluav taws xob hluav taws xob yog radially sab nraud los ntawm tus nqi zoo thiab radially mus rau qhov tsis zoo ntawm tus nqi
