GCSE Chemistry - Atoms & Ions #1

The video explores the structure of atoms, which are composed of a nucleus with protons and neutrons, surrounded by electrons. It explains the relative mass and charge of these particles, the size of atoms, and how they can form ions by gaining or losing electrons. The video also introduces the periodic table, explaining how atomic and mass numbers determine the identity of elements.

Describe the structure of an atom, including the arrangement of its particles.

How does the size of an atom compare to the size of its nucleus?

What is the relationship between the mass number and the number of neutrons in an atom?
