An element with half-filled 4p subshell belongs to which group
Correct answer: B. 15
- A. 14
- B. 15
- C. 13
- D. 16
Explanation
An element with a half-filled 4p subshell belongs to Group 15 of the periodic table. This is because elements in Group 15 have five electrons in their p subshell, which results in a half-filled configuration. In contrast, Group 13 elements start filling the p subshell with only one electron, Group 14 elements have four electrons in the p subshell, and Group 16 elements have six electrons, which is more than half-filled.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
