What is the different between atom and ion?

GCSE AQA chemistry
Atom: no charge. Same no. of protons and electrons.
Ion: charged. Different no. of protons and electrons.
e..g more electrons than protons: negative -
more protons than electrons: positive+

hope this helps

The number of protons stays the same in an ion, only the number of electrons change

An ion has a different number of electrons. If the number of protons change then it becomes another element.
An isotope has a different number of neutrons.
an ion is an atom (or group of atoms) that has gained or lost electrons
Hello guys
This is my flashcards for GCSE AQA Biology (Combined science trilogy)
Can someone check for me if I had covered all the topics needed for the GCSE exam?
For some flashcards, I'm also not entirely sure if the definition is correct or not.

Have you reviewed the specification?
Yeah, but I'm not 100% sure if I covered all the topics in my flashcards

You can be tested on anything in the spec.
