Muaj ntau txoj hauv kev ntawm kev faib cov ntsiab lus, tab sis lawv feem ntau muab faib ua hlau, semimetals (metalloids), thiab nonmetals. Koj yuav pom ntau pab pawg tshwj xeeb, xws li cov hlau hloov pauv, cov av tsis tshua muaj, cov hlau alkali, alkaline ntiaj teb, halogens, thiab cov roj av zoo.

Ntawm no, dab tsi yog pab pawg ntawm lub rooj zaum?

Pawg (lub sij hawm lub sij hawm)

  • Pawg 1: cov hlau alkali (lithium tsev neeg) * tsis suav nrog hydrogen.
  • Pawg 2: alkaline ntiaj teb hlau (tsev neeg beryllium)
  • Pawg 3-12: kev hloov pauv hlau.
  • Pawg 13: lub triels (boron tsev neeg)
  • Pawg 14: cov tetrels (carbon tsev neeg)
  • Pawg 15: pnictogens (tsev neeg nitrogen)
  • Pawg 16: cov chalcogens (oxygen tsev neeg)

4 hom ntsiab yog dab tsi? Classification ntawm cov Cov ntsiab lus Peb pawg no yog: hlau, nonmetals, thiab inert gases. Cia peb saib qhov twg cov pab pawg no nyob rau ntawm lub rooj sib tham thiab sib cuam tshuam nrog lawv lub peev xwm poob thiab nce electrons. Nco ntsoov, cov cwj pwm no yog qhov yooj yim dua. Ua ntej, cov hlau.

Yog li ntawd, dab tsi yog 7 pawg ntawm lub sij hawm?

Cov ntsiab lus nthuav tawm hauv txhua qhov Periodic Table Pawg yog Gas, Liquid lossis Solid nyob rau hauv chav tsev kub thiab muab faib rau hauv pab pawg xws li: Alkali Metals, Alkaline Earth Metals, Transition Metals, Metalloids, Other Metals, Non-metals, Halogens, Noble Gases and Rare Earth Elements.

Dab tsi yog Pawg 13 ntawm lub rooj sib tham hu ua?

Pawg 13 qee zaum hu ua boron pab pawg , npe rau thawj lub ntsiab hauv tsev neeg. Cov ntsiab lus no - tsis yog qhov xav tsis thoob - nyob hauv kab 13 ntawm daim ntawv qhia hnub . Qhov no pab pawg suav nrog boron, aluminium, gallium, indium, thallium, thiab ununtrium (B, Al, Ga, In, Tl, thiab Uut, feem).
