Arrange the following elements in the order of their increasing nonmetallic character Li, O, C, Be, F- F < O < C < Be < Li
- Li < Be < C < O< F
- F < O < C < Be < Li
- F < O < Be < C < Li
Correct answer: (d) F < O < Be < C < Li
Explanation: Li is on the left in the 2nd period of the modern periodic table followed by Beryllium. Fluorine is right next to Neon. Hence, Fluorine shows maximum non-metallic characteristics followed by Oxygen, Berrylium, carbon, and Lithium.
