Students will take the colored ions off the lab bench, put them in the labeled beakers.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ After you buy this worksheet todayYou will have an easy to use digit, My IGCSE Coordinated Science students were struggling with chemical formulas, reactions. In a neutral molecule, the charge of the cation is the same but opposite the charge of the anion. Do you need a digital activity to help your students learn the difference in, because they are spelled the same, which is why I created this digital sorting game that helps them use color to differentiate. Nomenclature is the process of naming chemical compounds with different names so that they can be easily identified as separate chemicals. Electron Configuration, the Periodic Properties HF (g) = hydrogen fluoride -> HF (aq) = hydrofluoric acid, HBr (g) = hydrogen bromide -> HBr (aq) = hydrobromic acid, HCl (g) = hydrogen chloride -> HCl (aq) = hydrochloric acid, H2S (g) = hydrogen sulfide -> H2S (aq) = hydrosulfuricacid.
