Answer» (a) The most reactive non-metal has high Δi H1 and Δi H2 and most negative ∆eg H Hence, the most reactive non-metal is I. (b) The least reactive non-metal has low Δi H1 and Δi H2 and less negative ΔegH. Hence, the least reactive non-metal is II. (c) The least reactive element has very high Δi H1 and Δi H2 and has positive ΔegH values. Hence, the least reactive element is III. |
