Atomic Structure
Akopọ
Everything you can touch, taste, or breathe is made from atoms. Although atoms are far too small to see with the naked eye, understanding their internal structure explains why elements behave the way they do, why the Periodic Table is arranged the way it is, and how chemical reactions happen.
In this lesson you will learn what atoms and molecules are, explore the sub-atomic particles inside every atom, and discover how atomic number and mass number define an element. You will also meet isotopes and learn how to calculate relative atomic mass from isotopic abundances.
Awọn Afojusun
- Know what is meant by the terms atom and molecule
- Know the structure of an atom in terms of the positions, relative masses and relative charges of sub-atomic particles
- Know what is meant by the terms atomic number, mass number, isotopes and relative atomic mass (Ar)
- Be able to calculate the relative atomic mass of an element (Ar) from isotopic abundances
