Q: Which s-block element has the highest atomic radius?
Solution: Rubidium (Rb) has the highest atomic radius among the given s-block elements.
Steps: 5
Step 1: Understand what s-block elements are. They are found in Group 1 and Group 2 of the periodic table.
Step 2: Identify the s-block elements. The main s-block elements include Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Barium (Ba).
Step 3: Know that atomic radius generally increases as you move down a group in the periodic table.
Step 4: Compare the atomic radii of the s-block elements. As you go down the group from Lithium to Rubidium, the atomic radius increases.
Step 5: Conclude that Rubidium (Rb), being lower in the group than the others, has the largest atomic radius among the s-block elements.
