Have you ever seen an atom?

Have you ever seen at atom? Seeing as everything is made of them, you have. But have you ever seen one on its own? Over time, microscopes have
become more and more powerful, allowing us to see deeper into
the world of the ultra-small. Traditional light microscopes can be
used to see things like these onion cells and the structures within them as they
divide, pulling apart their chromosomes. But scientists have come up with a whole host
of clever methods to observe far smaller things. Using beams of electrons instead of light, we can
generate detailed images of chromosomes themselves. Recently, groups of scientists
around the world are becoming able to see materials at the most
fundamental scale – the atomic. One group from the University of California in Los
Angeles have been getting up close and personal with nanoparticles of platinum,
just a few nanometres across. Each of the tiny dots you can see here
are actually individual platinum atoms. But researchers didn’t stop
at a two-dimensional picture. By imaging over 100 slices of the
nanoparticle at different angles then removing the
noise with a special filter, they were able to map the location
of almost every atom. The information was used to create
a three-dimensional reconstruction of the whole particle
in unprecedented detail. It may look blurry, but this particle is
estimated to contain over 27,000 atoms and so, like flies in a swarm,
they appear to merge together. Every so often, though, we see the platinum’s atomic
structure align, granting us a moment of clarity. This technique is being used to analyse tiny irregularities
in the structure of the particle called dislocations. Dislocations are subtle, like the misalignment of
the green and red layers of atoms in this particle. But nonetheless, they can significantly
change the properties of materials, with effects ranging from a change in the
efficiency of LEDs to the strength of metal alloys. Three-dimensional atomic-scale imaging
like this is bettering our understanding of the structure of materials on
this truly fundamental scale.

  1. Who watching this video from india .Plz reply me. And also clik a like .So nice video and very useful for students .Thanks plz make more videos like this .

  2. It seem like the atom has a electron-shell. The "color" of the surface of the electron-shell seems like "homogenous" per time which indicates that the electrons are there at "every point" on the electron-shell per time. No doubt that electrons are revolving round the nucleus at very high speed, to have electrons at every point on the electron-shell which implies that there are many electrons are revolving round the nucleus. In my research, we reckon that the absolute charge of 20 electrons is equal to the one of a proton. Why? The existence of so many types of super acids, mineral acids and weak acids suggest that the absolute charge of an electron is much weaker than the one of a proton. If acidity is caused by the single protons, then all of them should be exactly identical to one another therefore all different acids should have similar causticity. Wrong. Therefore the absolute charge of an electron should be much weaker than the one of a proton. Absolute charge of 20 electrons is equal to the one of a proton will give rise to many varieties of "single" proton each with different number of electrons within their electron-shell. If you are interested in real discoveries, I would recommend you to read my book, The Unification Theory – Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust.

  3. Yes ı see. Behind to my house yes fresh fruite juice shop he put in the side honey,banana,stawberry,walnut,nuts and milk after he mixed all this in blender its name is ATOM… What enteresting i dont understand 🤔

  4. We can simply calculate no. Of atoms or molecules in any object.
    1) find the composition of object, elements that it contains
    2) percentage of all these elements and then calculate their exact masses present in that object
    3) use their molecular mass and avagadro's constant ratio to calculate no. Of atoms of each element present in that object.
    4) add all the calculated data hence you'll find the approximated no. Of atoms/molecules present in that particular object.

  5. Sve te gluposti koje vi istrazujete su netacne. Upamtite ali bas dobro sve se desava voljom svemocnog boga alaha. Ja ne zelim ni da sam poznat na ovom svijetu I nikakve me titule ne interesuju.zelim samo jednom bogu alahu da se mollim I sto vise dobrih djela da uradim ne da bi me vi hvalili jer to je mnogo lose.dovoljno mi je da mi bog alah zna. sto bi ste rekli da ste u blizini I jacini eksplozije od 10 mega tona?

  6. Porque mierda no dejan activado la opción de subtítulos en español???….es ciencia!!!…es una obligacion dejar activado los subtítulos en todos los idiomas posibles… 🙁

  7. Это чо атом ? Откуда свет на атоме ? Ведь свет это тоже частицы фотонов…

  8. Do you believe God exists?
    No, I don’t believe in anything I can’t see.
    Do you believe in atoms?
    Yes. They are the smallest particle that I can’t see.

  9. Yes, I have seen glaxies of them. A special technique can enable human's naked eye to see atoms. The size of nucleus is much larger than we know by today.
    Electron is like an orbital wave. Nucleus is dark sphere right in th the middle. I wish, some day, technology would be able to transport images from my brain to other display. Because it's worth experiencing to travel through extraordinary unvirse of tiny particles

  10. is any video available of atoms ?
    if you can click picture its also possible to click video
    i have a question

    neutrons moves around nucleus so it must look like atoms are marching
    for example see human march if you see them from distance there hand and legs moving its like syncing motion
    see this
    if its atom it must look like same because electrons moves around nucleus

    2 nd
    we can see world because photons are exist
    we are so huge compared to atoms so its possible
    A proton is about 1835 times more massive than an electron
    means equal size of proton
    proton diameter is around 0.001 pm atoms are around 100 pm different with different atoms
    means around 316×316 photons are responsible to get this image of one atom
    how its possible that atom loosing its 316×316 photons ( which is equal in size of proton ) every Milli seconds so that we can see it
