electronegativity

in a replacement reaction, which nonmetal would replace chlorine?
(1 point)
○ iodine
○ fluorine
○ bromine
○ astatine

Explanation:

In a replacement reaction, a more reactive non - metal can replace a less reactive non - metal. Fluorine is more reactive than chlorine. Fluorine has a higher electronegativity (as can be seen from the general trend in the periodic table where electronegativity increases across a period and decreases down a group, and fluorine is above chlorine in the halogen group).

Answer:

fluorine
