The atom of an element has electronic configuration 2, 8, 7. To which of the following elements would it be chemically similar?
N (7)
P (15)
Na (11)
F (9)

Academic Chemistry NCERT Class 10

Correct Answer: (d) F (9)

Explanation: The element would be chemically similar to F (9) as it has the same number of valence electrons. the electronic configuration of F is 2,7.
