Question

What is the element with the lowest electronegativity value? How do you determine this?

a. cesium
b. helium
c. calcium
d. fluorine

Answer 1

Electronegativity order, from lowest to highest is:

`cesium < calcium < helium < "fluorine"`

Explanation:

Electronegativity is greater the higher and to the right is an element in the Periodic Table. Therefore, it will be less the lower and left.

Some elements (like helium) have an abnormal electronegativity value, reported @truong-son-n in a very interesting comment that you can find below this explanation.
