Lub npe binary (ob- keeb ) covalent compounds zoo ib yam li npe yooj yim ionic tshuaj sib xyaw . Cov thawj lub ntsiab nyob rau hauv cov mis tsuas yog teev siv cov npe ntawm keeb . Qhov thib ob keeb yog lub npe los ntawm kev noj qia ntawm lub npe element thiab ntxiv cov suffix -ide.
Kuj paub, txoj cai rau npe cov khoom sib txuas yog dab tsi?
Cov cai rau npe yooj yim covalent compounds : 1. Lub npe uas tsis yog-hlau nyob deb tshaj plaws rau sab laug ntawm lub rooj sib tham los ntawm nws lub npe elemental. 2. Lub npe lwm yam uas tsis yog-hlau los ntawm nws lub npe elemental thiab ib qho -ide xaus.
Vim li cas peb thiaj siv cov lus ua ntej hauv kev naming covalent compounds? Vim muaj ntau tshaj ib tug atom ntawm txhua lub caij yog tam sim no, prefixes yog xav tau los qhia tus naj npawb ntawm atoms ntawm txhua tus. Raws li Table 2.6 " Prefixes rau Kev Qhia Tus lej ntawm Atoms hauv Tshuaj Cov npe ", cov ua ntej rau ob yog di-, thiab ua ntej rau plaub yog tetra-.
Tsis tas li ntawd, thaum naming binary covalent tebchaw lub caij sau ua ntej yuav yog ib qho uas kuv?
Thaum naming binary covalent tebchaw, lub caij uas teev ua ntej yuav yog ib tug uas yog xim hlau ntau dua. Covalent Bond - Txaus siab rau lub zog nruab nrab ntawm lub nuclei ntawm lub molecule lub atoms thiab khub ntawm electrons ntawm lub atoms.
Ib qho piv txwv ntawm covalent compound yog dab tsi?
A covalent daim ntawv cog lus ntawm ob qho tsis yog hlau los ntawm kev sib koom electrons, yog li ib qho piv txwv tuaj yeem yog "Dej, H2O" raws li nws yog tsim los ntawm kev sib koom ntawm electrons ntawm hydrogen thiab oxygen (uas yog ob qho tib si tsis yog hlau). Thiab lwm tus piv txwv ntawm covalent "Carbon dioxide, CO2".

Thaum naming ib compound nrog ib tug kev hloov hlau yuav xav tau dab tsi?
Tus yuam sij rau naming ionic compounds nrog kev hloov pauv hlau yog los txiav txim siab tus nqi ionic ntawm cov hlau thiab siv cov lej roman los qhia tus nqi ntawm cov hlau hloov pauv. Sau lub npe ntawm kev hloov pauv hlau raws li qhia nyob rau ntawm Lub Sijhawm Lub Sijhawm. Sau lub npe thiab them nyiaj rau cov tsis yog hlau

Organic compounds thiab inorganic compounds yog dab tsi?
Lub ntsiab sib txawv yog nyob rau hauv lub xub ntiag ntawm ib tug carbon atom; cov organic tebchaw yuav muaj cov pa roj carbon atom (thiab feem ntau yog hydrogen atom, tsim hydrocarbons), thaum yuav luag tag nrho cov inorganic tebchaw tsis muaj ib qho ntawm ob lub atoms. Meanwhile, inorganic tebchaw muaj xws li cov ntsev, hlau, thiab lwm yam elemental compounds
Tam sim no universal naming system siv rau naming kab mob yog dab tsi?
Nyob rau hauv 1758, Linnaeus tau npaj ib qho kev faib cov kab mob. Nws luam tawm nyob rau hauv nws phau ntawv, Systema Naturae. Hauv qhov system no, txhua hom tau muab lub npe ob feem; Vim li no, qhov system hu ua binomial nomenclature. Cov npe yog raws li cov lus thoob ntiaj teb: Latin
