General Introduction to Group 14 Elements
Covers electronic configuration, occurrence, variation of properties, oxidation states, and trends in chemical reactivity for Group 14 elements.
What is General Introduction to Group 14 Elements?
The reluctance of the valence s-electrons to participate in bonding in heavier elements of p-block groups, leading to a preference for oxidation states two units less than the group number.
Key points
- Identify the elements belonging to Group 14.
- State the general electronic configuration of Group 14 elements.
- Describe the trend in physical and chemical properties down the group.
- Explain the common oxidation states exhibited by these elements.
Common exam trap
Confusing the metallic and non-metallic character trends.
