Qhov sib txawv tseem ceeb ntawm arsenic thiab phosphorous yog tias arsenic yog nonmetal whereas phosphorous yog metalloid.
Arsenic thiab phosphorous yog ob qho tib si nyob rau hauv p block ntawm lub sijhawm ntawm cov ntsiab lus. Lawv tuaj yeem pom nyob rau hauv qhov zoo li cov zaub mov uas cov ntsiab lus no tshwm sim ua ke nrog lwm cov ntsiab lus xws li oxygen thiab sulfur. Txawm hais tias peb tsis tuaj yeem pom phosphorous hauv nws daim ntawv dawb huv, arsenic tuaj yeem pom ua cov khoom dawb.
Arsenic yog dab tsi?
Arsenic yog cov khoom siv tshuaj muaj atomic tooj 33 thiab cov cim tshuaj As. Thiab, cov tshuaj no tshwm sim raws li cov khoom siv grey xim hlau. Ntxiv mus, arsenic ib txwm tshwm sim hauv cov zaub mov sib txawv; e.g. ua ke nrog lwm cov khoom xws li sulfur thiab hlau. Txawm li cas los xij, peb tuaj yeem pom nws ua cov khoom siv lead ua ntshiab thiab. Tsis tas li ntawd, muaj ntau ntau yam sib txawv ntawm arsenic, tab sis cov isotope nrog cov xim hlau zoo li feem ntau yog siv rau hauv kev lag luam. Arsenic tshwm sim hauv cov xwm txheej raws li monoisotopic metalloid. Qhov ntawd txhais tau tias nws muaj ib qho isotope ruaj khov.
Daim duab 01: Arsenic
Dhau li ntawm, arsenic yog p-block keeb. Nws nyob hauv pawg 15 thiab lub sijhawm 4 ntawm lub sijhawm teem sijhawm. Cov txheej txheem electron ntawm no metalloid yog [Ar]3d104s24p3 Tsis tas li ntawd, qhov no metalloid yog nyob rau hauv ib tug solid-state ntawm chav tsev kub. Thaum cua sov, nws tuaj yeem raug sublimation.
Muaj peb hom allotropic ntawm arsenic: grey, daj thiab dub arsenic. Daim ntawv tshaj plaws thiab muaj txiaj ntsig yog grey arsenic. Cov qauv siv lead ua ntawm arsenic yog rhombohedral. Thaum xav txog nws cov khoom sib nqus, arsenic yog diamagnetic. Grey arsenic yog cov khoom siv nkig vim yog cov tshuaj tsis muaj zog ntawm cov txheej txheem ntawm allotrope.
Phosphorus yog dab tsi?
Phosphorous yog cov tshuaj muaj atomic tooj 15 thiab cov cim tshuaj P. Muaj ob lub ntsiab ntawm phosphorous li dawb thiab liab phosphorous. Txawm li cas los xij, vim nws qhov ua tau zoo heev, peb tsis tuaj yeem pom cov qauv dawb ntawm phosphorous.
Daim duab 02: Allotropes ntawm Phosphorous
Ntxiv mus, cov phosphorous dub yog cov thermodynamically ruaj khov allotrope ntawm phosphorous ntawm chav tsev kub. Nws tshwm sim hauv ob daim ntawv ua alpha daim ntawv thiab beta daim ntawv. Daim ntawv alpha yog qhov ruaj khov tshaj plaws allotrope thiab nws tsim thaum peb kub liab phosphorous ntawm 803K. Lub caij no, daim ntawv beta ntawm phosphorous cov ntaub ntawv thaum peb sov dawb phosphorous ntawm 473K.
Qhov txawv ntawm Arsenic thiab Phosphorus yog dab tsi?
Arsenic yog cov khoom siv tshuaj muaj atomic tooj 33 thiab cov cim tshuaj As. Phosphorous yog ib yam tshuaj muaj atomic tooj 15 thiab tshuaj cim P. Qhov tseem ceeb sib txawv ntawm arsenic thiab phosphorous yog arsenic yog nonmetal whereas phosphorous yog metalloid.
Ntxiv mus, peb tuaj yeem pom arsenic ua cov tshuaj dawb huv hauv daim ntawv siv lead ua thaum peb nrhiav tsis tau phosphorous hauv nws daim ntawv dawb huv vim muaj qhov ua haujlwm siab.
Hauv qab infographic qhia txog qhov sib txawv ntawm arsenic thiab phosphorous.
Summary – Arsenic vs Phosphorus
Arsenic thiab phosphorous yog ob qho tib si nyob rau hauv p block ntawm lub sijhawm ntawm cov ntsiab lus. Lawv tuaj yeem pom nyob rau hauv qhov zoo li cov zaub mov uas lawv tshwm sim ua ke nrog lwm cov ntsiab lus xws li oxygen thiab sulfur. Txawm li cas los xij, peb tsis tuaj yeem pom phosphorous hauv nws daim ntawv ntshiab, tab sis arsenic tuaj yeem pom tau ua cov khoom dawb. Qhov sib txawv tseem ceeb ntawm arsenic thiab phosphorous yog arsenic yog nonmetal whereas phosphorous yog metalloid.
