Which of the following elements is most electropositive?
Correct answer: C. Be
- A. C
- B. N
- C. Be
- D. O
Explanation
The most electropositive element among the given options is beryllium (Be). Electropositivity refers to the ability of an element to donate electrons, and it typically increases as you move down and to the left on the periodic table. Beryllium, being a metal, has a greater tendency to lose electrons compared to non-metals like carbon (C), nitrogen (N), and oxygen (O), which are more likely to gain electrons. Therefore, Be is the most electropositive among the given choices.

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.
