A quarter is huge compared to an atom. To put them in perspective let's calculate how many atoms are in a US quarter:
-The current US quarter has a mass of 5.67g and is 8.33% nickel and 91.67% copper.
-From the mass and percentages of each element we can find that there are 5.20g of copper and 0.472g of nickel in each quarter.
-Dividing the mass of each element by its molar mass we find that there are 0.0818 moles of copper and 0.00805 moles of nickel in each quarter.
-Multiplying the number of moles of each element by Avogadro's number we find that there are 4.93x1022 atoms of copper and 4.85x1021 atoms of nickel in each quarter.
This means there is a total of 5.41x1022 atoms in a US quarter. Let's write that number out to get a little more perspective:
54,100,000,000,000,000,000,000
That certainly is a huge number!
The nucleus of an atom is very small compared to the size of the whole atom. The nucleus makes up only a tiny fraction of the atom's total volume, while the rest of the atom (which is mostly empty space) is occupied by the electron cloud.
The atom is about 10,000 times as big as the nucleus.
The nucleus of an atom is very small compared to the overall size of the atom. It contains protons and neutrons, which make up almost all of the atom's mass, but occupy a tiny fraction of its volume. The rest of the atom is mostly empty space where electrons move around.
