Which of the following elements shows maximum valence electrons?

AF

BAl

CH

DN

Answer:

A. F

Read Explanation:

  • Fluorine (F) has the maximum number of valence electrons (7).

  • The fluorine element is located in group 17 and period 3 on the periodic table.

  • Elements from group 17 are classified as halogens.

  • This class of elements are highly electronegative atoms that possess a total of seven valence electrons in their highest occupied molecular orbital.
