The elements arsenic and Antimony are considered as:
Correct answer: C. Metalloid
- A. Metals
- B. Non metal
- C. Metalloid
- D. None of the above
Explanation
Arsenic and Antimony are classified as metalloids. Metalloids are elements that have properties of both metals and nonmetals. Arsenic and antimony are situated in the p-block of the periodic table and have properties intermediate between those of a metal and a nonmetal. They have metallic luster and are semiconductors, but they are brittle and can be easily broken. They can also act as either an oxidizing agent or reducing agent in chemical reactions, depending on the conditions.

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.
