Study Notes
Periodic Table
- The periodic table is a chart that organizes elements by their atomic number and properties.
- The vertical columns of the periodic table are called Groups and are numbered 1 to 8.
- "A series" elements are representative or main group elements.
- "B series" elements are transition or subgroup elements.
- Group 1A metals are called the alkali metals.
- Group 2A metals are called the alkaline earth metals.
- Group 7A elements are called the halogens.
- Group 8A elements are called the rare gases or noble gases.
Elements
- Each horizontal row of the periodic table is called a period.
- The Lanthanide series consists of elements cerium (Z = 58) to lutetium (Z = 71).
- The lanthanide series is also sometimes called the rare earth series.
- The Actinide series consists of elements thorium (Z = 90) to lawrencium (Z = 103).
Electron Configuration
- 1s is the first energy level in the electron shell.
