Study Notes
Periodic Table Overview
- The periodic table organizes elements by atomic number, symbol, and average atomic mass.
- Elements are grouped based on similar chemical properties, facilitating understanding of their behavior.
Groups and Periods
- The columns in the periodic table are known as groups.
- The rows are referred to as periods.
Group 1: Alkali Metals
- This group consists of highly reactive soft metals.
- Alkali metals have one electron in their outer shell, contributing to their high reactivity.
Group 2: Alkaline Earth Metals
- Alkaline earth metals are located in Group 2.
- They react less vigorously than alkali metals, requiring the loss of two electrons for a full outer shell.
Group 7: Halogens
- Halogens are found in Group 7 and possess seven electrons in their outer shell.
- Reactivity among halogens decreases as one moves down the group.
Group 0: Noble Gases
- Noble gases occupy Group 0 and are characterized by being colorless and unreactive.
- Their density decreases as one moves down the group.
Transition Metals
- Transition metals are known for their use as catalysts in various chemical reactions.
