Which of the following is not a characteristic of interstitial compounds of transition elements?
(a) The formulae of these compounds do not correspond to any normal oxidation state
(b) They have melting points higher than those of pure elements
(c) They are very hard and some compounds approach diamond in hardness
(d) They are insulators in contrast to the transition metals
Answers
I hope the is the correct answer I am not sure
Answer: (d) They are insulators in contrast to the transition metals is incorrect statement.
Explanation:
Transition elements are the d block elements.
They are known as transition elements because their properties are intermediate between s block and p block.
S block elements are highly electropositive elements.
P block are highly electronegative elements.
We'll read each option and see if it's wriye or wrong.
a) The formulae of these compounds do not correspond to any normal oxidation state
It is correct.
(b) They have melting points higher than those of pure elements
It is correct
(c) They are very hard and some compounds approach diamond in hardness.
It is correct.
(d) They are insulators in contrast to the transition metals
It is incorrect.
They show metallic property and hence are not insulators.
