Question

1. which of the following elements has the largest atomic radius? 1 point og fr al ge

Explanation:

Step1: Recall atomic - radius trend

Atomic radius increases down a group and decreases across a period in the periodic table.

Step2: Locate elements in periodic table

Og (Oganesson) is a noble - gas in period 7, group 18. Fr (Francium) is an alkali metal in period 7, group 1. Al (Aluminum) is in period 3, group 13. Ge (Germanium) is in period 4, group 14.

Step3: Compare atomic radii

Since Francium is in the lowest period among these elements and is in the left - most group among them (metals have larger radii than non - metals in the same period), it has the largest atomic radius.

Answer:

Fr
