Element that is around god (6)
I believe the answer is:
iodine
'element' is the definition.
(iodine is a kind of element)
'that is around god' is the wordplay.
'that is' becomes 'ie' (abbreviation for id est, 'that is' in Latin).
'around' means one lot of letters goes inside another.
'god' becomes 'odin' (Norse god).
'ie' placed around 'odin' is 'IODINE'.
(Other definitions for iodine that I've seen before include "Solution of a halogen in ethyl alcohol used on wounds as an antiseptic" , "Hanging tuft" , "Solution applied to wounds as an antiseptic" , "Black/violet element" , "for therapeutic purposes" .)
