Study Notes
Periodic Trends
- Elements in the same period on the periodic table exhibit similar chemical and physical properties due to the same number of electron shells.
Proton and Metallic Nature
- As you move from one element to the next in a period, the number of protons increases, and the metallic nature generally decreases.
Group Properties
- Elements in the same group (column) of the periodic table exhibit similar chemical and physical properties due to the same number of electrons in the outermost energy level.
Halogen Electronic Configuration
- Halogens in group 17 tend to have a full outer energy level, except for one electron.
Periodic Table Structure
- As of 2022, there are 7 complete periods in the periodic table.
Blocks and Properties
- Elements within the same period generally do not exhibit trends and similarities in properties in the f-block.
Periodic Trends Explanation
- The periodic trends in properties of elements on the periodic table are explained by the periodic variation in atomic size, electronegativity, and electron configuration.
Halogen Position
- Halogens, such as group 17 elements, lie on the right side of the periodic table.
