Which of the following elements has properties like that of P?

Correct answer: C. Sb

  • A. Se
  • B. Ge
  • C. Sb
  • D. Te

Explanation

The correct answer is Sb (Antimony). Phosphorus (P) is in group 15 of the periodic table, known as the nitrogen group or pnictogens. Elements in the same group typically have similar chemical properties due to having the same number of valence electrons. Antimony (Sb) is also in group 15, hence it shares properties with phosphorus. Selenium (Se), Germanium (Ge), and Tellurium (Te) belong to different groups, which exhibit different properties compared to phosphorus.

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.
