Which of the following elements forms maximum number of compounds?
Correct answer: C. Hydrogen
- A. Carbon
- B. Silicon
- C. Hydrogen
- D. Fluorine
Explanation
The correct answer is Hydrogen. Hydrogen is a part of water, one of the simplest and most abundant compounds, and forms a vast number of organic compounds. It can bond with almost every element in the periodic table, making it involved in forming the maximum number of compounds. Carbon is known for forming a large number of compounds, mainly organic, but hydrogen's universality in compound formation is broader. Silicon, while forming numerous compounds, especially in the form of silicates, does not match hydrogen's versatility. Fluorine, though highly reactive, does not form as many compounds as hydrogen.

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.
