Question 3

In the modern periodic table, how do electronegativity and metallic character generally change as one moves from left to right across a period?

Accepted Answer

B. Electronegativity tends to increase, while metallic character tends to decrease. — Across a period from left to right, the nuclear charge increases and the atomic radius generally decreases, leading to a stronger attraction for valence electrons, hence electronegativity increases. Concurrently, the tendency to lose electrons decreases, and the tendency to gain electrons increases, causing the metallic character to decrease and non-metallic character to increase.

Answer

A. Both electronegativity and metallic character tend to increase.

Answer

C. Electronegativity tends to decrease, while metallic character tends to increase.

Answer

D. Both electronegativity and metallic character tend to decrease.

Question 9

Kerala's agricultural sector faces significant challenges including fragmentation of land holdings, labor shortages, and climate change impacts. Which of the following strategies is most likely to enhance the long-term sustainability and productivity of agriculture in Kerala, considering these constraints?

Accepted Answer

B. Implementing precision farming techniques, encouraging organic farming, and supporting farmer producer organizations (FPOs). — Option B presents a comprehensive and sustainable approach. Precision farming optimizes resource use, organic farming improves soil health and resilience against climate change, and FPOs help overcome land fragmentation by enabling collective action and better market access for small farmers. Monoculture (A) can degrade soil and increase vulnerability. Shifting to non-food crops (C) might compromise food security and environmental balance.
