About This Product
Each model shows the orientation of the bonds around a central atom, so students can compare shapes from linear to octahedral. The 2 extra pear-shaped parts allow protonated models, for example in acid/base theory, where H3O+ forms as H+ migrates from hydrogen chloride. Lone pairs appear as brown parts, which helps this Molecular Model set explain shapes such as bent water and pyramidal ammonia.
Frequently Asked Questions
Q1. Which molecules does the Shapes of Molecules Set model? Hydrogen chloride, beryllium chloride, water, boron trihydride, ammonia, methane, phosphorus pentachloride and sulphur hexafluoride.
Q2. Can it show protonated molecules? Yes. 2 extra pear-shaped parts allow protonated models, e.g. the formation of H3O+ as H+ migrates from hydrogen chloride.
