At the microscopic level, the size of atoms is truly mind-boggling. To put things in perspective, let’s start with something relatable: the human hair. An individual hair measures about 100 micrometers, which is a millionth of a meter. At this scale, we have already surpassed the limits of our naked eyes, as individual hair cells can be as small as 10 micrometers.
As we delve deeper into the world of atoms, things start to become even more perplexing. At the atomic level, we are dealing with measurements in picometers, which are trillionths of a meter. This is where the human imagination starts to falter, struggling to comprehend the unimaginably small size of atoms.
Electron orbitals enclose the atoms, but even beyond that, we have a long journey ahead of us before reaching the atom’s nucleus. The nucleus of an atom consists of protons and neutrons, which are measured in femtometers. One femtometer is equivalent to one thousandth of a trillionth of a meter. It is an incredibly minuscule scale that requires sophisticated tools and instruments to explore.
To gain a deeper insight into the atomic realm, advanced technology has been developed, such as electron microscopes. These cutting-edge devices utilize accelerated electrons instead of photons to illuminate microscopic specimens, enabling scientists to delve into the nanoscale with unprecedented precision.
Electromagnets within electron microscopes function as lenses, steering and focusing the electron beam onto the specimen.
