To determine which element has the largest atomic radius among Silicon (Si), Phosphorous (P), Aluminum (Al), and Sulfur (S), let's examine their respective atomic radii.
We have the following atomic radii for these elements:
- Silicon (Si): 111 pm
- Phosphorous (P): 98 pm
- Aluminum (Al): 143 pm
- Sulfur (S): 88 pm
To find the element with the largest atomic radius, we compare these values:
1. Silicon (Si) has an atomic radius of 111 pm.
2. Phosphorous (P) has an atomic radius of 98 pm.
3. Aluminum (Al) has an atomic radius of 143 pm.
4. Sulfur (S) has an atomic radius of 88 pm.
Clearly, among the given atomic radii, Aluminum (Al) has the largest value, which is 143 pm.
Thus, the element with the largest atomic radius is Aluminum (Al).
