In which period is the most electronegative element found :
Correct answer: B. 2
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
The most electronegative elements are found in Period 2 of the periodic table. Electronegativity is the tendency of an atom to attract electrons towards itself when it is involved in a chemical bond. In general, electronegativity tends to increase across a period from left to right in the periodic table. In Period 2, the elements from lithium (Li) to neon (Ne) are located. Fluorine (F) is the most electronegative element in this period, followed by oxygen (O). These elements have high electronegativity values because they have a strong attraction for electrons due to their atomic structure.

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.
