 Which element is not malleable: Au, Zn, Cu, or C?
The word malleable means it can be hammered into thin sheets.

Au is the symbol for gold which is a metal and it is very malleable.

Zn is the symbol for zinc which is a metal and it is very malleable.

Cu is the symbol for copper which is a metal and it is very malleable.

C is the symbol for carbon which is a nonmetal and it is not malleable.

 Group I elements form compounds with this group...
Group 17.  For example Sodium (Na) of Group I forms a compound with Chlorine 
(Cl) of Group 17 and the compound is Sodium Chloride (NaCl).
