Krypton, for example, and iodine — strange mixture (5,3)
I believe the answer is:
inert gas
'krypton for example' is the definition.
I can't tell whether this defines the answer.
'iodine strange mixture' is the wordplay.
I cannot really understand how this works, but
'iodine' could be 'i' (chemical symbol) and 'i' is present in the answer.
an anagram of 'strange' is 'nertgas' which is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for inert gas that I've seen before include "He perhaps" , "Eg, helium or argon" , "Such as neon or xenon" , "He, amongst others" , "Eg, krypton or argon" .)
