Is gold made of atoms or molecules?
Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In a pure form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal.
Are gold and silver made out of atoms?
Gold, copper and silver are composed of atoms. More extensive information is available at Atom – Wikipedia and Molecule – Wikipedia . Gold,copper and silver are the elements of group-11 which are known as coinage metals.
Is copper a molecule or compound?
Copper is an element made up of copper atoms. If it were made up of more than one kind of atom, it would be a compound. Water is a compound because it is made up of water molecules. There is no such thing as water atoms.

Is gold an example of a molecule?
Gold, silver, sodium, lithium etc. are examples of an element. As we know, all the elements represent an atomic number, it depends on the number of protons inside the nucleus.
What is silver composed of?
Natural silver consists of a mixture of two stable isotopes: silver-107 (51.839 percent) and silver-109 (48.161 percent). The metal does not react with moist air or dry oxygen but is oxidized superficially by moist ozone. It is quickly tarnished at room temperature by sulfur or hydrogen sulfide.
What elements is gold made of?
Gold is the chemical element with 79 protons in each atomic nucleus. Every atom containing 79 protons is a gold atom, and all gold atoms behave the same chemically. In principle, we can therefore create gold by simply assembling 79 protons (and enough neutrons to make the nucleus stable).
How many protons are in copper?
29
Copper/Atomic number
All copper atoms have atomic number 29: all their nuclei contain 29 protons. But they also contain uncharged particles called neutrons. In natural copper, the atoms are of two kinds. One has 29 protons and 34 neutrons in the nucleus; the other has 29 protons and 36 neutrons (Figure 4).
Is copper made of molecules?
Copper is a metal, not a molecule.
What atoms is copper made of?
Natural copper is a mixture of two stable isotopes: copper-63 (69.15 percent) and copper-65 (30.85 percent). Copper electrical cables. Because of copper’s high electrical conductivity, it is heavily used in the electrical industry.
