Question

Discuss the trends in electronegativity and atomic radii for elements of group 16 17, 18. 

Answer 1

Trends in electronegativity and atomic radii for elements of group 16, 1 7, 18:

Electronegativity: Electronegativity decreases as atomic size increases down the group. As a result, the top elements in each group (e.g., Oxygen in Group 16, Fluorine in Group 17) are the most electronegative.

Atomic radii: Atomic radii increase down the group as the number of electron shells increases. This results in weaker nuclear attraction on the outermost electrons, making the atomic size larger.
