Question

Transcribed Image Text:Place the following in order of increasing atomic radius.
Options:
1. ○ As < Br < O
2. ○ O < As < Br
3. ○ Br < As < O
4. ○ As < O < Br
5. ● O < Br < As
Explanation: This is a question that asks you to arrange elements based on their atomic radius. Atomic radius generally increases as you move down a group in the periodic table, and decreases as you move across a period from left to right. The correct order based on atomic radius for the elements listed—oxygen (O), bromine (Br), and arsenic (As)—is O < Br < As. Thus, the fifth option is highlighted as correct.
