Edexcel IAL Chemistry AS 2.5 Isotopes
Edexcel IAL Chemistry AS 2.5 Isotopes
State that atoms of the same element share proton number but differ in neutron number, then calculate or compare the requested particle counts from the notation.
How this is tested
- Define isotopes as atoms with the same proton number but different neutron numbers.
- Use isotope notation or tables to compare atomic number, mass number and neutrons.
