Question

Reactivity of transition elements decreases almost regularly from Sc to Cu because of (A) lanthanoid contraction (B) regular increase in ionisation enthalpy (C) regular decrease in ionisation enthalpy (D) increase in number of oxidation states

Reactivity propto (1/ text I.E ) Since Ionisation enthalpy increases from Sc to Cu, reactivity decreases from Sc to Cu

Q. Reactivity of transition elements decreases almost regularly from $S c$ to $C u$ because of

lanthanoid contraction

regular increase in ionisation enthalpy

regular decrease in ionisation enthalpy

increase in number of oxidation states

Reactivity $\propto \frac{1}{I.E}$
Since Ionisation enthalpy increases from $S c$ to $C u$ , reactivity decreases from $S c$ to $C u$
