Handy reference: List of ions, orbitals, equations & constants

When you’re getting started with Chemistry, the volume of information thrown at you can seem overwhelming.

Students taking the cbsquared Chemistry for GAMSAT course have a host of resource documents available to them in the course already, but I thought I would post a few extra online resources with a few great images to help you form a visual picture of the building blocks of chemistry at the molecular level.

Please note: here is no need to rote learn any of this material for the GAMSAT!

1. Table of common polyatomic ions with 3D models.

Once you get to topic 2 and 3, we start talking about lewis dot structures and it can be helpful to be familiar with some common polyatomic ions.

2. Orbitron, a website with images showing what the orbitals and hybridised orbitals look like in 3D

Useful for understanding what an atomic orbital might look like, and also for the hybridisation topic, to get an idea of what hybrid orbitals look like.




3. Lists of useful equations and physical constants used in physical chemistry.*

*PLEASE NOTE: You do not need to rote learn these equations or physical constants. They will be provided in the stimulus of the GAMSAT question. You should learn the very basic equations, such as c = n/v and n = m/M for chemistry questions.

For more information about how the cbsquared Chemistry for GAMSAT course can help you achieve your GAMSAT and medical school goals, or just for some guidance and advice about how to kick start your study, please feel free to get in touch.
