Thaum theformula chav tsev muaj ob lossis ntau dua ntawm tib yam polyatomicion , uas ion yog sau nyob rau hauv kab lus nrog cov subscript sau sab nraum cov kab lus.

Kuj tseem yuav paub, qhov txawv ntawm qhov sib xyaw thiab polyatomic ion yog dab tsi?

Cov tshuaj yog cov koom haum uas feem ntau tuaj yeem cais tawm raws li lawv tau sau yam tsis xav tau lwm yam. Lawv tuaj yeem tsim los ntawm ions , molecules, molecular ions , zwitterions, hlau atoms, thiab lwm yam. Ions yog chargedspecies. Ua ke nrog counterions ntawm opposite nqi, lawv tuaj yeem ua tau tshuaj sib xyaw.
