Solution

The correct option is B

Li<Be<C<O<F


The explanation for the correct option

(B) Li<Be<C<O<F

The trend of nonmetallic character:

  • Nonmetallic character increases across a period on moving from left to right in the periodic table.
  • This occurs as a result of an atom's increasing number of electrons and protons as it moves from left to right in a period.
  • Due to the increased nuclear force on the electrons, as a result, losing electrons becomes difficult.
  • It decreases on moving down in the group in the periodic table.
  • One moving down the group, atomic radius increases, making things easier to lose electrons.
  • Chlorine and oxygen are the most electronegative elements.

Order of nonmetallic character

  • The non-metallic character is an element's tendency to accept electrons and form negative ions or anions.
  • The modern periodic table's second period, which contains li and beryllium, is on the left.
  • Fluorine is a chemical element that is right next to Neon.
  • After oxygen, beryllium, carbon, and lithium, fluorine exhibits the most non-metallic characteristics.
  • The order of nonmetallic character is as follows:

Li<Be<C<O<F

The explanation for incorrect options

  • The order of nonmetallic character is Li<Be<C<O<F.
  • Hence all other options (A), (C) and (D) are incorrect.

Therefore, the correct option is (B) Li<Be<C<O<F.
