Question

what are properties of typical transition elements?
also tell why elements of Zn grp and Sc grp are regarded as non typical transition elements?
with detail pls...
ONLY RELEVANT ANSWERS!!!​

Answer 1

Answer:

properties of typical transition elements:

• form stable complexes.
• Have high melting and boiling points.
• Contain large charge/radius ratio.
• Form compounds which are often paramagnetic.
• Are hard and possess high densities.
• Form compounds with profound catalytic activity.
• Show variable oxidation states.

Explanation:

Transition metals are the elements with a partially filled d orbital in their valence layer. Zinc is 4s2 3d10, meaning the d orbital is filled, and so is the neighbouring s orbital (as opposed to Cu, for example).Thus, Zn does not react quite like a transition metal, but more like a main-group metal like Mg. In fact, Zn is closer in reactivity to Mg than to, say, Mn or Ti.
