Which among the following properties is \(\underline{NOT}\) exhibited by transition elements?

A These are generally hard.
B These form alloys with other metals.
C These do not conduct heat.
D These are malleable and ductile.

Verified Solution

Answer & Solution

Correct Answer

(C) These do not conduct heat.

Step-by-step Solution

Detailed explanation

- Transition elements do conduct heat well, as they are good conductors of both heat and electricity.
- They are typically hard, can form alloys with other metals, and are also malleable and ductile, which are common properties of metals in general.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
