Increasing attraction between the nuclei of atoms and their outer-shell electrons with increasing atomic number across a period produces greater electronegativities. number across a period produces smaller electronegativities. number across a period produces greater electronegativities. B. Decreasing attraction between the nuclei of atoms and their outer-shell electrons with increasing atomic C. Decreasing attraction between the nuclei of atoms and their outer-shell electrons with increasing atomic

Explanation / Answer

Electronegativity of an element is directly proportional to its nuclear charge and inversely proportional to its atomic size

Electronegativity increases in period due to increase in nuclear charge and decrease in size and

Electronegativity decreases in group due to decrease in nuclear charge and increase in size

Answers:

PART 1: A

Part 2: C
