How many atoms are in Pen?

Answer 1

The number of atoms in a pen can vary depending on its materials and design, but a typical plastic pen contains thousands to millions of atoms. For example, a plastic pen primarily made of polymers can have around 10^23 atoms, as polymers are made up of long chains of repeating molecular units. Additionally, pens often contain metal components, which would add to the total atom count. Thus, the total number of atoms in a pen can easily reach into the millions or more.
