Faahfaahinta casharka

Natiijada casharka

Waxaan qeexi karaa astaamaha gaasaska gobta, isticmaalkooda, iyo sharaxaadda sababta ay u yihiin kuwa aan falgalin.

Hordhac

Soo dhawoow casharkaan oo ku saabsan Kooxda 0, gaasaska gobta (noble gases) oo ka tirsan qaabka diyaarinta (periodic table). Anigu waxaan ahay Mr. Gundry, oo maanta si wada jir ah u soo mari doona casharkaan. Waxaan rajeynayaa inaad xiisaynaysid, sababtoo ah aniguna waan xiisaynaa. Gaasaska gobta waa curiyeyaal (elements) aad u xiiso badan. Marka aan dhammayno casharkaan, waa inaad awood u yeelataa inaad qeexdo sifooyinka gaasaska gobta, adeegsigooda, iyo sababta ay u yihiin kuwa aan falcelin (unreactive).

Muuji qoraalka
Noble gases are in Group 0 of the periodic table and are unreactive. Noble gases are all gases at room temperature. They have complete outer electron shells, making them stable. Moving down Group 0 elements, atomic mass, density and boiling points increase.
