Question

16 multiple choice 1 point select the atom with the highest ionization energy. sb as p n

Explanation:

Ionization energy increases across a period and decreases down a group in the periodic table. N (nitrogen), P (phosphorus), As (arsenic), and Sb (antimony) are in Group 15. N is at the top - most position among them, so it has the highest ionization energy due to its small atomic size and high effective nuclear charge.

Answer:

D. N
