Faahfaahinta casharka

Natiijada casharka

Waxaan sharxi karaa waxa curiye kiimiko (chemical element) yahay iyo tusaalooyin ka mid ah.

Hordhac

Ku soo dhawoow casharkayaga maanta oo ku saabsan atamka iyo curiyeyaasha (elements). Kani waa qayb ka mid ah cutubka loo yaqaan 'Atoms, Elements and Compounds'. Kahor intaadan bilaabin, waa inaad hore u taqaan fikradda maaddada (matter) iyo in walax kastaa ay ka kooban tahay atam (atom) yaryar.

Muuji qoraalka

All matter is made up of atoms. Dalton’s model of an atom is of a sphere that cannot be broken up. An element is made up of only one type of atom. Each element is made of a different type of atom.
