Which of the following element has the different value of electronegativity than other three:A H B S C C D I

To answer this question, we need to know the electronegativity values of each of the elements mentioned. Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used electronegativity scale.

Here are the electronegativity values on the Pauling scale for each of the elements:

A. Hydrogen (H) - 2.20 B. Sulfur (S) - 2.58 C. Carbon (C) - 2.55 D. Iodine (I) - 2.66

Looking at these values, we can see that Hydrogen (H) has a significantly different electronegativity value compared to the other three elements. Therefore, the answer is A. Hydrogen (H).
