  1. Ionic sib tov / Molecular Compound npe.
  2. Thaum twg naming compounds, thawj qhov koj yuav tsum tau ua yog txiav txim siab yog lub compound yog ionic los yog molecular .
  3. Saib ntawm cov ntsiab lus hauv qhov sib xyaw.
  4. * Ionic tebchaw yuav muaj ob qho tib si hlau thiab tsis yog hlau, los yog tsawg kawg yog ib tug polyatomic ion.
  5. * Molecular cov tebchaw yuav muaj tsuas yog cov hlau tsis muaj hlau.

Ntawm no, dab tsi yog lub ntsiab lus molecular?

A molecular keeb yog a molecular cov khoom muaj xws li ib leeg keeb , xws li H2, F2, Cl2, Br2, I2, O2, O3, P4, S8.

Ib yam li ntawd, dab tsi yog qhov piv txwv ntawm cov khoom molecular? cov ntsiab lus molecular (diatomic molecules ) hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (br2), iodine (I2) cov ntsiab lus molecular.

Ib yam li ntawd, tib neeg nug, ua li cas chemists paub tias lub molecule zoo li cas?

Txoj hauv kev tseem ceeb yog siv x-ray crystallography. X-rays tawg tawm ntawm atoms thiab molecules thiab tsim cov duab uas yog Fourier hloov ntawm cov qauv. Tom qab ntawd los ntawm kev ua lej ntau thiab simulations lawv muaj peev xwm rov tsim cov qauv uas yuav tsim cov duab x-ray.

Dab tsi yog diatomic element?

Diatomic molecules yog cov molecules tsim los ntawm ob lub atoms, ntawm ob qho tib si los yog sib txawv tshuaj cov ntsiab lus . Cov cov ntsiab lus diatom yog: Bromine, Iodine, Nitrogen, Chlorine, Hydrogen, Oxygen, thiab Fluorine. Txoj hauv kev kom nco ntsoov lawv yog: BrINClHOF thiab Tsis Txhob Ntshai Npias Dej Txias.
