Write any four differences between lanthanoids and actinoids.
Lanthanoids
Actinoids

Text Solution

AI Generated Solution

To differentiate between lanthanoids and actinoids, we can consider the following four key differences: 1. **Electron Configuration**: - **Lanthanoids**: The last electron enters the 4f orbital. - **Actinoids**: The last electron enters the 5f orbital. 2. **Color**: - **Lanthanoids**: Some lanthanoids are colorless, while others are colored. ...
