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.
A penny weighs 2.5 grams and is 2.5% copper. Therefore, there is
2.5 grams × .025 = .0625 grams of copper in a penny
Then you convert grams to atoms with the molecular weight of copper and Avogadro's constant
.0625 grams ÷ 63.5 grams/mol × (6.02 × 1023 atoms) ÷ 12 in one dozen = 4.94 × 1019 dozens of copper atoms
3.0 x 10^22 / 500
= 6 x 10^19 reams
short answer: 22long answer: 2.04 X 10^22 atoms of copper
This depends on the mass of this penny.
Number of atoms = [(Mass of the coin) x 6,022.10e23]/63,546.

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.

Copper is an element. You can have a single atom or many atoms and it's still copper.
The answer is 47,128 x 1023 atoms.

Copper is normally encountered as metal which is a giant lattice of atoms.
Copper sulfate (CuSO4) has 6 atoms and 3 chemical elements.
