Biraha Kooxda 1 iyo 2
Waxaan ku soo dhaweynayaa casharkan ku saabsan birta kooxda 1aad iyo 2aad, oo ka tirsan cutubka 'Patterns in the periodic table'. Kahor intaadan daawashadan bilaabin, waa inaad hore u taqaanid sida loo isticmaalo diiwaanka xilliyada (periodic table) iyo sida loo aqoonsado kooxaha (groups) iyo xilliyada (periods). Casharkani wuxuu ku barayaa sida ay birtaani u falceliso, isagoo ku lug leh tijaabo (experiment) xiiso leh.
Natiijada casharka
Waxaan qeexi karaa qaabka falcelinta biraha kooxda 1 ee biyaha iyo biraha kooxda 2 ee asiidhka khafiifka ah, oo waxaan isbarbardhigi karaa falcelinta labada koox.
