Kev tshuaj xyuas cov ntsiab lus, cov khoom sib xyaw, thiab cov khoom sib xyaw
| Ionic Cov tshuaj | Covalent Cov tshuaj |
|---|---|
| Sib cais rau hauv cov khoom siv hluav taws xob hauv dej kom muab cov kev daws teeb meem hluav taws xob | Nyob twj ywm li qub molecule hauv dej thiab yuav tsis ua hluav taws xob |
Tsuas yog li ntawd, lub zog puas yog cov khoom sib xyaw lossis sib xyaw?
Zog tsis yog ib qho ntawm no. Cov ntsiab lus , tshuaj sib xyaw thiab sib tov yog txhua yam teeb meem. Zog tsis muaj teeb meem, vim nws tsis muaj huab hwm coj lossis nyob hauv qhov chaw.
Pizza yog ib qho khoom xyaw lossis sib xyaw? Yog li pizza tsis yog a compound . Nws yog ib sib tov Muaj ntau ntau yam xws li khob noom cookie, ntses, nqaij, veggies, cheese, thiab lwm yam. sib tov ntawm lwm yam xws li cov proteins, starches, qab zib, dej, fiber, vitamins, minerals, thiab lwm yam lub ntsiab compound los yog a sib tov ?
Tom qab ntawd, lo lus nug yog, hluav taws xob puas yog lub hauv paus?
Tsis muaj. Hluav taws xob , yog chained ntws ntawm electrons ntawm molecules. Koj Element yog kev sib xyaw ntawm tag nrho cov khoom - nucleons (protons thiab neutrons) nrog cov electrons hauv lawv lub plhaub. Hluav taws xob conductivity yog ib tug feature / cwj pwm ntawm txhua tus keeb (a) lossis molecules (b), hluav taws xob tsis yog ib Element nws tus kheej.
Qab Zib puas yog ib qho khoom xyaw lossis sib xyaw?
Qab Zib yog a compound . Nws yog ib qho tshuaj sib xyaw ua ke ntawm carbon, hydrogen, thiab oxygen. Yog! Zaub xam lav yog ib sib tov.

Puas yog Oxygen yog cov khoom sib xyaw lossis sib xyaw?
Puas yog oxygen yog ib qho khoom sib xyaw lossis sib xyaw? Oxygen yog ib yam khoom. Nws yog tsim los ntawm tib hom atom, oxygen atoms (8 protons). Nws tshwm sim kom ruaj khov tshaj li molecules ntawm muaj pes tsawg leeg
Dab tsi yog hom hluav taws xob hluav taws xob sib txawv?
Qhov sib txawv ntawm cov hluav taws xob hluav taws xob muaj nyob hauv cov hluav taws xob hluav taws xob muaj xws li xov tooj cua tsis muaj zog, microwaves, infrared tsis, pom lub teeb, ultraviolet hluav taws xob, X-rays, thiab gamma rays. Ib feem ntawm cov electromagnetic spectrum uas peb tuaj yeem pom yog qhov pom lub teeb spectrum
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
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
