'show some attractions of chemistry' is the definition.
I can't judge whether this definition defines the answer.

'i wasted coins engaging agent' is the wordplay.
'wasted' indicates an anagram.
'engaging' indicates putting letters inside (inserted letters are engaged or involved in others).
'agent' becomes 'bond' (James Bond).
'coins' with letters rearranged gives 'onics'.
'onics' placed around 'bond' is 'onicbonds'.
'i'+'onicbonds'='IONIC BONDS'

'to' acts as a link.
