Sicela ngomusa RATE & WABELANE lolu hlelo lokusebenza njengoba kuba :-) khulula
Ithebula gqwa kuyinto ukubonisa tabular samakhemikhali, ihlelwe ngesisekelo nezici zabo. Elements ethulwa Ziyanda athomu. Umzimba omkhulu etafuleni kuyinto igridi 18 × 7, izikhala kufakwe ukugcina izakhi izakhiwo efanayo ndawonye, ezifana halogens kanye amagesi zasebukhosini. Lezi izikhala yakha ezindaweni ezine ezihlukene, aboncamane nofana amabhlogo. I f-block akufakwanga etafuleni main, kodwa kunalokho ngokuvamile bentanta ngezansi, njengoba uxhumekile kwi-inthanethi f-block ibingenza etafuleni impractically ububanzi. Ithebula gqwa ebikezela ngokunembile izakhiwo izakhi ehlukahlukene uhlobano phakathi izakhiwo. Ngenxa yalokho, it inikeza uhlaka ewusizo ehlaziya chemical ukuziphatha, futhi sisetshenziswa kabanzi ku-chemistry neminye imikhakha yesayensi.
