Study Notes
The Modern Periodic Table
- Chemists developed the modern periodic table, as the structure of the atom was better understood
- The periodic table helps to see patterns in the properties of elements
- There are 100+ elements, all materials are composed of these elements
- Elements are arranged in order of increasing atomic number (proton number)
- The periodic table shows repeating patterns in the properties of elements
- It's useful for quickly identifying elements as metals or non-metals
- Elements with similar properties form columns (groups)
- The vertical columns are called groups
- The elements in a group usually have the same number of electrons in their outer shell
- The elements in a group are likely to react in a similar manner
- The rows are called periods, each new period represents another full shell of electrons
- The periodic table is a useful tool for understanding chemical behaviour
