Study Notes
Introduction to the Periodic Table
- The Periodic Table is a chart that lists all the known elements.
- The table is arranged in a way that elements with similar properties are placed in the same group.
- The version of the Periodic Table used today was first proposed by Dmitri Ivanovich Mendeleev in 1872.
What is on the Periodic Table?
- Each element is represented by a tile that includes:
- Chemical symbol
- Atomic number
- Mass number
- The table is arranged in a way that elements with similar properties are placed in the same group.
How are the Elements Arranged?
- The element with the smallest atomic number (Hydrogen) is in the top left corner of the table.
- Elements are arranged in regions, often presented in different colors.
- Metals, non-metals, and semi-metals are grouped together.
Identifying Elements
- Each element has a unique name, chemical symbol, and atomic number.
- Metals are found on the left of the Periodic Table.
- Non-metals are found in a triangular region at the top right of the table.
- Semi-metals (or metalloids) have metallic and non-metallic properties and are found in a diagonal strip on the right-hand side of the table.
Key Concepts
- Periods are the horizontal rows of the Periodic Table.
- Groups are the vertical columns of the Periodic Table.
- Atomic and mass numbers can be found on each element's tile.
- Being able to interpret group and period numbers is important.
