Gold has metallic bonds.
The electrons of the gold atoms are delocalised to form a sea of electrons. The gold atoms are held together by electrostatic forces of attraction between the negatively charged sea of electrons and the positively charged ions (the nucleus + the electrons that are not delocalised). Gold has high melting and boiling points because a lot of energy is required to overcome this strong electrostatic forces of attraction.
