Faahfaahinta casharka

Natiijada casharka

Waxaan sharxi karaa molecule (molecule) oo sawiri karaa sawirada curiyeyaasha ka kooban molecules.

Hordhac

Ku soo dhawoow darsiga maanta ee curiyeyaasha molecular. Waa qayb ka mid ah cutubka atoms, curiyeyaasha, iyo compounds. Waa inaad hore u garanaysaa sida loo aqoonsado curiyeyaasha shaxda xilliyeedka (periodic table) iyo in atoms-ku ay yihiin qaybaha ugu yar ee arrimaha.

Muuji qoraalka
Many non-metals are in the gas state at room temperature. Some non-metals form diatomic molecules that contain two atoms (e.g. O₂, N₂, H₂, Cl₂). Some non-metals are monatomic and do not form molecules. Noble gases are monatomic and are listed in the right-hand column of the periodic table.
