Pab pawg 15 yam yaj thiab cov ntsiab lus kub

Nitrogen muaj qhov qis tshaj melting point thiab kub point.

Raws li, cov hlau twg muaj qhov tsawg tshaj plaws melting point?

Mercury

Tsis tas li ntawd, dab tsi yog suav tias yog qhov qis melting point? " Melting "yog lo lus siv nyob rau hauv physics los qhia thaum ib qho khoom hloov mus rau hauv cov kua, Mercury yog ib qho khoom ntawm heev. qis kub, tab sis nws " yaj " ntawm li 10 degrees Fahrenheit. Yog li - Mercury muaj a qis melting point , ntau qis tshaj Hlau.

Nyob rau hauv kev hwm rau qhov no, lub ntsiab lus twg muaj qhov qis tshaj melting thiab boiling point?

Helium

Puas yog Pawg 1 cov hlau puas muaj cov ntsiab lus melting tsawg?

Alkali hlau muaj qis melting thiab boil Cov ntsiab lus Tag nrho Pawg 1 cov ntsiab lus muaj ib qho electron nyob rau hauv lawv lub plhaub sab nraud uas yog tuav tsis muaj zog los ntawm cov nucleus. Qhov nce atomic radius txhais tau tias tsis muaj zog ntawm cov atoms thiab yog li a qis melting thiab boil taw tes.

Puas yog gallium muaj qhov melting qis tshaj plaws?

Lub melting point rau gallium (uas yog sawv cev rau ntawm Lub Sijhawm Table li Ga) yog qhov qis, ntawm 85.6 ° F (29.8 ° C). Txawm li cas los xij, qhov kub ntawm cov khoom no yog siab heev, ntawm 4044 ° F (2229 ° C). Qhov kev ua tau zoo no ua rau gallium zoo tagnrho rau kev sau cov ntsuas kub uas yuav ua kom puas lub ntsuas kub

Cov pab pawg twg ntawm cov ntawv teev sijhawm twg yog cov tshuaj chlorine?

Chlorine belongs rau pab pawg neeg ntawm halogens - ntsev tsim - ua ke nrog fluorine (F), bromine (Br), iodine (I) thiab astatine (At). Lawv tag nrho nyob rau hauv kab thib ob los ntawm sab xis ntawm lub rooj sib tham hauv Pawg 17. Lawv cov teeb tsa hluav taws xob zoo sib xws, muaj xya lub tshuab hluav taws xob hauv lawv lub plhaub sab nraud

Dab tsi feem ntau yog pab pawg ua haujlwm thiab vim li cas cov pab pawg no tseem ceeb?

Cov pab pawg ua haujlwm tau txuas mus rau carbonbackbone ntawm cov organic molecules. Lawv txiav txim siab tus yam ntxwv thiab tshuaj lom neeg reactivity ntawm molecules. Cov pab pawg ua haujlwm tsis tshua muaj kev ruaj ntseg dua li cov pa roj carbon monoxide thiab zoo li yuav koom nrog cov tshuaj tiv thaiv

Vim li cas cov ntsiab lus hauv Pab Pawg 1 yog qhov cuam tshuam tshaj plaws?

Qhov feem ntau reactive nyob rau hauv pab pawg neeg 1 yog caseium vim hais tias thaum peb los ntawm sab saum toj mus rau hauv qab, qhov luaj li cas ntawm atom yog nce nyob rau hauv lub parallel nrog cov xov tooj ntawm electron, yog li lub zog tuav lub electron txo, thiab peb paub tias tag nrho cov alkali hlau muaj. ib qho hluav taws xob nyob rau hauv lub plhaub feem ntau yog li nws tuaj yeem yooj yim tshem tawm qhov ntawd
