Waxaan sharxi karaa farqiga u dhexeeya isku-dhis (compound) iyo curiye (element).
Hordhac
Soo dhawoow darsiga maanta ee ku saabsan xeryahooda (compounds) iyo sida ay u samaysmaan. Waa qayb ka mid ah cutubka loo yaqaan Atoms, Elements, and Compounds. Waa inaad hore u garanaysaa waxa ay yihiin curiyeyaasha (elements) iyo atom-yada, si aad u fahanto sida ay isugu xirmaan xeryahooda.

6. Maxay tahay sababta ay iskudhisyada (compounds) u leeyihiin astaamo (properties) ka duwan curiyeyaasha (elements) laga sameeyay?
- Curiyeyaashu waxay illoobaan astaamahooda.
- Jawaabta saxda ah:Iskudhisku waa kiimiko (chemical) gebi ahaan ka duwan curiyeyaasha laga sameeyay.
- Iskudhisyadu had iyo jeer way beddelaan astaamahooda.
- Birta (metals) kaliya ayaa sameysa iskudhisyo.
