Why is it not possible to see an atom?

Question

What are the different parts of atoms made of? You have e-, p+, and neutrons, but are those made up of anything? We also say atoms are the smallest pieces of matter, but electrons, neutrons and protons are proven to have mass so would they technically be the smallest pieces of matter?

Answer 1

We cannot see atoms because they are too small, obviously. Another reason would be that atoms cannot reflect light by themselves (but an enormous group of atoms or molecules, like a table, could).
Protons and neutrons are made from particles called quarks. There are Up, Down, Top, Bottom, Strange and Charming quarks. Protons are made of two Up and one Down quark. Neutrons are made from two Down and one Up quark. I have not really got this clear about electrons though, but, to my understanding, if you add a proton and an electron, you get a neutron. So an electron must be what an Up quark needs to have to turn into a Down quark. Atoms are by no means the smallest parts of matter. Then there are the subatomic particles, and then there are quarks.

Answer 2

People claim to have "seen" atoms with scanning tunneling microscopy. They "scan" a surface with a needle with avanishingly small point. Through the accumulation of electrons that "tunnel" through the barrier between needle and substrate, persons claim to have images of "knobs" on surfaces of substrates.

Answer 3

why do u think? atoms make up everything you cant see an atom unless u have a hell of a microscope

Answer 4

because it's too small to see with the naked eye

Answer 5

they are extremely small to see with the naked eye.

Answer 6

quarks, leptons, neutrinos,
