Arrange the given non-metals in the increasing order of their electronegativity. Atomic number is given in parentheses.

O (8), Te (52), S (16), Se (34)

Correct option is D

The correct answer is (D)   ​Te < Se < S < O

Information booster:

• Oxygen (O) has the highest electronegativity among these elements, with an electronegativity value of 3.44 on the Pauling scale. Oxygen is a small atom with a high ability to attract electrons.

• Sulfur (S) has an electronegativity of 2.58. It is in the same group as oxygen but is located lower, so its electronegativity is lower.

• Selenium (Se), with an electronegativity of 2.55, is located below sulfur in the periodic table and has a slightly lower electronegativity.

• Tellurium (Te) has the lowest electronegativity of the group at 2.01. It is in the same group as the other elements but is further down, and so it has a lower ability to attract electrons.
