Which of the following has the highest electronegativity value among group 16 elements? a Sulfur b Selenium c Tellurium d Oxygen

The correct answer is d) Oxygen.<br /><br />Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. In the periodic table, electronegativity increases as you move from left to right across a period and decreases as you move down a group.<br /><br />Group 16 elements, also known as the chalcogens, include oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and polonium (Po). Among these elements, oxygen has the highest electronegativity value.<br /><br />The electronegativity values of the group 16 elements are as follows:<br /><br />- Oxygen (O): 3.44<br />- Sulfur (S): 2.58<br />- Selenium (Se): 2.55<br />- Tellurium (Te): 2.1<br />- Polonium (Po): 2.0<br /><br />Therefore, among the given options, oxygen (d) has the highest electronegativity value.
