Sorry I have no ideaa ! :D
Metal bond like in all alloys
a metallic bond
Shi* ummmm.......metallic
There is gold oxide, Au2O3 But gold usually does not form compounds
Copper and gold.
Metals like copper and silver are added to gold by a goldsmith to make jewelry harder as gold in its pure form is soft, technically in liquid form. Adding metals, also makes gold cheaper and more affordable.
a metallic bond
No. They will most likely form an ionic bond. Metallic bonds form between the atoms of a metal, such as gold or iron.

Metallic bonding is found in gold or copper

Mercury will form a thin film on a clean copper sheet, and in this form, is used to capture very fine or dissolved gold. And clean copper is very easy to solder.
Copper have about half of the density of gold. Copper is melted together with gold to make an alloy, which can then be beaten into various patterns. Gold 24 carats refers to the purest (99%) gold. 22 carats (91% gold) and 18 carats (75% gold).
Copper, silver, and gold.
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.
Gold has a gold color, is softer ( try scratching it in a unobtrusive place), and it is NOT magnetic. Copper is very hard, has a bronze color, and at least has a weak magnetic field. Copper is also less dense that gold and is a better conductor of heat and electricity. Copper will tarnish over time while gold will never tarnish.
