Question

which of the following elements has the lowest electronegativity?
○ bromine
○ fluorine
○ lithium
○ carbon

Explanation:

Electronegativity increases across a period from left to right and decreases down a group in the periodic table. Lithium is an alkali metal (Group 1), carbon is in Group 14, bromine is a halogen (Group 17), and fluorine is also a halogen (Group 17, higher up than bromine). Alkali metals have relatively low electronegativities compared to non - metals like carbon, bromine, and fluorine.

Answer:

lithium
