Today, we know that atoms do not represent the smallest unit of matter. Particles called quarks and leptons seem to be the fundamental building blocks – but perhaps there is something even smaller. Physicists are still far from understanding why a proton has about 2,000 times more mass than an electron.

about 50 micrometersThe smallest object observable to the unaided human eye is about 50 micrometers (1 micrometer is 10-6 meters, one millionth of a meter). This is pretty much the diameter of the average human hair (17-180 micrometers, depending on color).

Can an atom die?

Since an atom has a finite number of protons and neutrons, it will generally emit particles until it gets to a point where its half-life is so long, it is effectively stable. … It undergoes something known as “alpha decay,” and it’s half-life is over a billion times longer than the current estimated age of the universe.

Can you see sperm with the human eye?

What are plant cells that are dried out?

Seeds are plant cells that are all dried out.

What is the smallest thing in life?

quarksProtons and neutrons can be further broken down: they’re both made up of things called “quarks.” As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.
