Question

is the element with highest electronegativity.

• A. Chlorine
• B. Fluorine
• C. Bromine
• D. Hydrogen
• E. Iodine
• F. Sodium

Answer 1

The correct option is B Fluorine

Non-metals that short of one to three electrons to attain stable configuration are called electronegative elements and they tend to gain electrons from other atoms. Fluorine, compared to other elements in the period, requires only one electron to complete an octet and attain stability. In addition to that it has the smallest atomic radius in its group. So, its valence electrons are bound to the nuclei stronger than any other element. Therefore, fluorine is the most electronegative element.
