A US 1 cent piece prior to 1982 was made of copper and had a mass of about 3.1g. This is about 0.049 moles of copper, or around 2.9 x 1022 atoms.
More recent pennies are mostly zinc (97.5%) and have a mass of about 2.5g. This works out to around 2.2 x 1022 zinc atoms and 5.9 x 1020 copper atoms, so overall around 2.3 x 1022 atoms.

How many copper atoms in a penny made of pure copper and weight 2.15g?
A penny made of pure copper has a mass of 2.5g and an atomic mass of copper is 63.55 g/mol. Calculate the number of moles in 2.5g of copper, then use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of copper atoms. This calculation would yield approximately 1.44 x 10^22 copper atoms in a penny.
Does a penny have more atoms than earth does people?
Yes, most definitely, a penny has many more atoms than the Earth does people.A pre-1982 penny contains about 28,000,000,000,000,000,000,000 copper atoms. Or, 2.8 x 1022atoms.There are about 6 billion people on the planet.
How many atoms does Cu2O?
Copper(I) oxide (Cu2O) contains 3 atoms: 2 copper atoms and 1 oxygen atom.
How many atoms are in copper phosphate?
Copper phosphate has the chemical formula Cu3(PO4)2. To determine the number of atoms, you need to add up the atoms in each element present. In this case, there are 3 copper atoms, 2 phosphorus atoms, and 8 oxygen atoms, totaling 13 atoms in copper phosphate.

How many atoms of copper are there in 497.3 grams of copper?
The answer is 47,128 x 1023 atoms.
How do the copper atoms in a penny stick together?
Metallic bonding - the metal atoms share their valence, or "outer" electrons. The electrons of many nuclei situate themselves between positively charged nuclei. Two or more nuclei are then attracted to the same valence electrons, causing them to "stick together" as a solid piece of metal.
