18 / 40

Category: Chemistry

18. Which of the following factors contribute to the low electronegativity of cesium compared to other elements?

i. Its large atomic radius significantly reduces nuclear attraction for bonding electrons.
ii. Cesium has a low ionisation energy which correlates with low electronegativity.
iii. The single valence electron in cesium is poorly shielded from the nucleus.
iv. Cesium has a high electron affinity which compensates for its low nuclear attraction.
v. Electron shielding from inner shells greatly diminishes effective nuclear charge.

19 / 40

Category: Chemistry

19. Which of the following statements correctly explain(s) why the electron affinity of phosphorus is less negative than that of sulfur?

i. Phosphorus has a half-filled p-orbital which is relatively stable.
ii. Additional electron in phosphorus would cause electron pairing, increasing electron-electron repulsion.
iii. Sulfur’s larger atomic radius reduces the repulsion experienced by the incoming electron.
iv. Phosphorus has a lower nuclear charge compared to sulfur.
v. The energy released upon adding an electron to phosphorus is offset by the loss of half-shell stability.
