Electronegativity

Vedclass · Answer

(A) Across a period,the atomic size decreases due to an increase in effective nuclear charge. As a result,the attraction for electrons increases,leading to an increase in both $Electronegativity$ and $Ionization 	ext{ } Potential$. $Electronegativity$ increases continuously across a period from left to right. While $Electron 	ext{ } affinity$ generally increases,it does not show a perfectly progressive increase due to stable electronic configurations (e.g.,noble gases). Therefore,$Electronegativity$ is the most accurate answer for a progressive increase.

Which of the following properties displays a progressive increase with the rise in atomic number across a period in the periodic table?
