Waxaan sharxi karaa sifooyinka curiyeyaasha birta ah (metallic elements) oo aan barbardhigi karaa kuwa aan birta ahayn (non-metal elements).

Hordhac

Ku soo dhawoow darsiga maanta ee curiyeyaasha birta ah (metallic elements). Waa qayb ka mid ah cutubka Atamka, curiyeyaasha iyo isku-dhisyada. Kahor intaadan bilaabin, waa inaad hore u garanaysaa sida atamka u yihiin dhismaha aasaasiga ah ee walxaha oo aad kala saari karto curiye (element) iyo isku-dhis (compound).

Muuji qoraalka

Metals are good thermal and electrical conductors, they are strong, shiny, malleable and ductile. Non-metals are normally poor thermal and electrical conductors, they are not strong, and are dull and brittle. Graphite is a non-metal that is a good electrical and thermal conductor. Metals are found on the left side and in the middle of the periodic table, non-metals on the right side.

Imtixaannada

1. Waa kuwee kuwan soo socda ay yihiin sifooyin jireed (physical properties) oo ah kuwa walxaha leeyihiin?
- Jawaabta saxda ah:heerkulka dhalaalida iyo karkarinta (melting and boiling points)
- samaynta walxo cusub marka biyo lagu daro
- qaadista korantada (conducting electricity)
- falcelinta oksijiinka (reacting with oxygen)
- dhalaalida (being shiny)
2. Mid ka mid ah kuwan soo socda ayaa ah walax saafi ah (pure substance)?
- Cabbitaan liin macaan oo cusub
- liin la isku qasay (orange squash)
- Jawaabta saxda ah:biyo la safeeyay (distilled water)
3. Marka sodium birta ah lagu daro gaaska chlorine, waxaa soo baxa olol huruud-jaalle ah iyo adke cad. Dooro waxa dhacay iyo sababta.
- Isbeddel jireed (physical change)
- Jawaabta saxda ah:Isbeddel kiimiko (chemical change)
- Walax cusub ayaa samaysmay
- Walxihii isku mid ah ayaa weli jira
- Sodium iyo chlorine ayaa falgaleen (reacted)

1. Waa kuwee astaamahan (properties) ee ugu badan inay la xiriiraan birta (metals)?
- Jawaabta saxda ah:Inay tahay kaxeeye wanaagsan oo kulaylka (thermal conductor)
- Inay tahay mid jaban (brittle)
- Inay tahay mid aan fiicneyn oo koronto qaada (poor electrical conductor)
- Inay tahay mid la qaabayn karo (malleable)
2. Garaafit waa bir aan ahayn (non-metal). Maxay tahay sababta ay u tahay mid gaar ah?
- Jawaabta saxda ah:Waa mid si fiican u gudbiya kulaylka iyo korontada (thermal and electrical conductor).
- Waa mid dhawaaq soo saarta (sonorous).
- Waxay ku taallaa dhinaca bidix ee shaxda xilliyeedka (periodic table).
- Waa mid dhalaalaya oo la jiidi karo (shiny and ductile).
3. Waa maxay macnaha 'malleable' (la qaabayn karo)?
- Jawaabta saxda ah:Waa wax si fudud loo qaabayn karo ama loo laablaabi karo.
- Waa wax si fudud u jajaba.
- Waa wax koronto qaadi kara.
- Waa wax la soo jiidi karo oo silig noqon kara.
4. Fiiri shaxda hoose oo dooro curiye (element) ayaa u badan inuu yahay bir (metal).
- Jawaabta saxda ah:Curiye A
- Curiye B
- Curiye C
5. Run ama been? Curiyeyaasha (elements) ee cagaarka ku muujisan sawirkan dhamaantood waa bir (metal) miyaay yihiin?
- Run
- Jawaabta saxda ah:Been
- hydrogen waa bir aan ahayn (non-metal)
- dhamaantood waa bir aan ahayn (non-metals)
