To determine the correct order of the elements in increasing atomic radius, we need to compare the atomic radii of Ca, Cl, K, and S.

1. Start by comparing Ca and Cl. Chlorine (Cl) is in Group 17 of the periodic table, while Calcium (Ca) is in Group 2. As we move down a group, the atomic radius generally increases. Therefore, Cl has a larger atomic radius than Ca.

2. Next, compare Cl and S. Both chlorine (Cl) and sulfur (S) are in Group 16. Again, as we move down a group, the atomic radius generally increases. Therefore, S has a larger atomic radius than Cl.

3. Now, compare Ca and K. Potassium (K) is in Group 1, while Calcium (Ca) is in Group 2. As we move down a group, the atomic radius generally increases. Therefore, K has a larger atomic radius than Ca.

4. Finally, compare S and K. Both sulfur (S) and potassium (K) are in Group 16. Again, as we move down a group, the atomic radius generally increases. Therefore, K has a larger atomic radius than S.

Based on these comparisons, the correct order of the elements in increasing atomic radius is: Cl

Question

To determine the correct order of the elements in increasing atomic radius, we need to compare the atomic radii of Ca, Cl, K, and S.

2. Next, compare Cl and S. Both chlorine (Cl) and sulfur (S) are in Group 16. Again, as we move down a group, the atomic radius generally increases. Therefore, S has a larger atomic radius than Cl.

3. Now, compare Ca and K. Potassium (K) is in Group 1, while Calcium (Ca) is in Group 2. As we move down a group, the atomic radius generally increases. Therefore, K has a larger atomic radius than Ca.

4. Finally, compare S and K. Both sulfur (S) and potassium (K) are in Group 16. Again, as we move down a group, the atomic radius generally increases. Therefore, K has a larger atomic radius than S.

Based on these comparisons, the correct order of the elements in increasing atomic radius is: Cl < S < Ca < K.
