Lesson 1.2 - Atomic model, atomic number/mass and isotopes
Learning Goals: By the end of this lesson you will be able to
- Describe the difference between the terms: Atomic Number (AN); Atomic Mass (AM); Isotope; Atomic Mass Unit (amu).
- Compare and contrast between Atomic Number (AN) and Atomic Mass (AM).
- Calculate neutron number from AM and AN.
- Distinguish Isotopes from regular elements or atoms.
- Write a formula of an Isotope using from AM and AN.
- Calculate relative atomic mass from given data of isotopes.
Success Criteria: By the end of this lesson you will be able to
- have a clear concept of Atomic Number (AN); Atomic Mass (AM); Isotope; Atomic Mass Unit (amu) and methods to calculate relative atomic mass from given data of isotopes.
