Pawg 15: Cov Nitrogen Tsev Neeg . Cov tsev neeg nitrogen suav nrog cov tshuaj hauv qab no: nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), thiab bismuth (Bi). AllGroup 15 cov ntsiab lus muaj cov khoom siv hluav taws xob2np3 nyob rau hauv lawv lub plhaub sab nrauv, qhov twg n yog tus lej quantum.

Kuj paub yog, dab tsi yog tsev neeg lossis pab pawg ntawm nitrogen?

Qhov no pab pawg tseem hu ua tsev neeg nitrogen . Nws muaj cov ntsiab lus nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi), thiab tej zaum cov tshuaj tsis muaj tshuaj lom neeg cov khoom siv moscovium (Mc). Nyob rau hauv niaj hnub IUPAC cim, nws yog hu ua Pab pawg 15.

Ib sab saum toj no, lub hauv paus ntsiab lus ntawm nitrogen yog dab tsi? Nitrogen tau tshawb pom los ntawm Daniel Rutherford (GB) hauv 1772. Lub keeb kwm ntawm npe los ntawm Greekwords nitron noob lub ntsiab lus nitre thiab sib sau thiab Latin lus nitrum (nitre yog ib hom npe rau potassiumnitrate, KNO3). Nws yog xim tsis muaj xim, tsis muaj ntxhiab, feem ntau inert gas, minimally reactive nyob rau hauv chav tsev kub.

Tsuas yog li ntawd, yog vim li cas nitrogen nyob rau hauv pab pawg 15?

Pawg 15 (VA) muaj nitrogen , phosphorous, arsenic, antimony, thiab bismuth. Cov ntsiab lus hauv Pawg 15 muaj tsib valence electrons. Vim hais tias cov ntsiab lus tuaj yeem tau txais peb lub tshuab hluav taws xob lossis poob tsib kom tau txais kev teeb tsa ruaj khov, lawv feem ntau tsim covalent tebchaw tshwj tsis yog kev sib koom ua ke rau ib qho activemetal.

Leej twg nrhiav tau lub tsev neeg nitrogen?

Keeb kwm thiab kev siv: Nitrogen yog nrhiav pom los ntawm tus kws kho mob Scottish Daniel Rutherford hauv xyoo 1772. Nws yog qhov thib tsib tshaj plaws hauv ntiaj teb thiab tsim txog li 78% ntawm lub ntiaj teb satmosphere, uas muaj kwv yees li 4,000 trillion tons ntawm thegas.
