MCQ
Among the elements given below, the element with the least electronegativity is :
  • ✓
    Lithium
  • B
    Carbon
  • C
    Boron
  • D
    Fluorine
✓

Answer

Correct option: A.
Lithium
(a) Lithium
Explanation : Electronegativity generally increases across a period (from left to right) in the periodic table and decreases down a group (from top to bottom). Since lithium is in the alkali metal group (Group 1) of the periodic table and is located in the far left, it has the lowest electronegativity among the options provided.
