Element tribe used with hesitation (7)

Ross

I believe the answer is:

terbium

'element' is the definition.
(terbium is a kind of element)

'tribe used with hesitation' is the wordplay.
'used' is an anagram indicator.
'with' means one lot of letters go next to another.
'hesitation' becomes 'um' (um is said in hesitation).
'tribe' with letters rearranged gives 'terbi'.
'terbi'+'um'='TERBIUM'
