GCSE Chemistry - Elements, Isotopes & Relative Atomic Mass #2

The video tutorial explains atomic structure, focusing on protons, neutrons, and electrons. It discusses how elements are organized in the periodic table by atomic number, which is determined by the number of protons. The concept of isotopes is introduced, highlighting that they are variations of elements with different neutron counts but the same number of protons. The tutorial also covers how to calculate the relative atomic mass of an element using the abundance and mass of its isotopes, using copper as an example.

Why might some element symbols be confusing, such as sodium being represented as 'Na'?

Describe the differences between carbon-12 and carbon-13.

What does the symbol 'AR' represent in chemistry?
