Question

1. determine which element has the largest atomic radius based on the location in the periodic table. periodic table mn p k cs

Explanation:

Step1: Recall atomic radius trend

Atomic radius increases down a group and decreases across a period.

Step2: Analyze element positions

• \(Mn\) (manganese) is in period \(4\), group \(7B\).
• \(P\) (phosphorus) is in period \(3\), group \(5A\).
• \(K\) (potassium) is in period \(4\), group \(1A\).
• \(Cs\) (cesium) is in period \(6\), group \(1A\).

Since \(Cs\) is in the lowest period among these elements (period \(6\)) and in group \(1A\) (where atomic radius is relatively large in the group), it has the largest atomic radius.

Answer:

\(Cs\)
