JEE Main Chemistry question

Which of the following properties show gradual decrease with increase in atomic number across a period in the Periodic Table? [Jamia Millia Islamia 2004]

(A)Electron affinity
(B)Ionisation potential
(C)Electronegativity
(D)Size of atomCorrect

Answer: (D)

Solution

Increasing nuclear charge across a period pulls the electron cloud inward, so atomic size steadily decreases from left to right. Electron affinity, ionisation potential and electronegativity all
