C2: The Atomic Structure

Here is a set of cards on the structure of an atom, from the C2 (chemistry) section of the course. This is mainly for students taking AQA Additional Science. I hope these revision cards will help you to revise! Please rate and comment on how they can be improved :) Also, I have a study group called AQA Additional Science where we discuss this topic and more. Feel free to become a member, the more the merrier!

Basic Atomic Structure

The nucleus = made of protons and neutrons

The electrons orbit around the nucleus

Proton = +1 charge

Neutron = 0 charge

Electron = -1 charge

The number of electrons is equal to the number of protons

Atoms have an overall charge of 0 - they are neutral

Electrons orbit the nucleus on energy levels (shells)

The Periodic Table

In the periodic table, the columns are called groups and the rows are called periods

the group number = the number of electrons on the outer most shell

the period number = the number of shells
