Is there anything smaller then an "Atom?"?

Question

And if there is, what is the smallest known entity?

Answer 1

Particles are smaller than atoms, such as electrons, protons, neutrons, and quarks. They comprise the atoms.

Answer 2

The smallest known entity, sizewise, is the electron, whose size appears to be zero (but can't be exacly zero, due to quantum mechanical constraints but is in any case too small to measure). The nucleus of an atom, containing all of its protons and neutrons, is typically smaller than the electron orbitals by a factor of 10^5 in radius.

Answer 3

Atoms are large composite structures of enormous sized, compared to electrons and such. In the Standard Model of high energy physics, some particles are considered "elementary'. This means the SM does not model any degrees of freedom associated with physical; they are mathematically treated as point particles. However, the SM is widely recognized to be only and "effective" particle model, pending a more fundamental one yet to be discovered. That is, they are not assumed to actually be points.

The most popular lead for a fundamental theory involves treating the particles as manifestations of little multidimensional strings, whose size is the order of the Planck length. Google that.

Answer 4

Yes, there is a very well-defined sub-atomic structure; protons, neutrons and electrons are made up of smaller particles. It's a complex field; however, the link below will give you a good introduction.

Answer 5

yes. there are particles that are smaller than an atom such as protons ,neutrons , electrons and even quarks! there is plenty more where that came from.

Answer 6

yes. protons and neutrons and electrons are inside the atom. and then inside the protons are quarks.

Answer 7

Protons, neutrons, and electrons make up atoms.
Quarks and neutrenoes make up those subatomic particles.

Answer 8

Yes there is! There is neutrons, protouns, electrons, neutrenoes, quarks are just some of them!!

Answer 9

Uncle Pennybags is appropriate. The GOP has given lip-provider to small government, yet in no way delivered. I undergo in innovations returned to Nixon, besides the actuality that i replaced into quite too youthful to undergo in innovations his rules first-hand. yet what small-government administration could ever impose a salary and value freeze? that's as "massive government" because it gets, yet Nixon did it. enable's no longer forget we went thoroughly off the main marvelous in the process the Nixon years. Ford, for as little a time as he served, looked as though it may pick to scientific care a number of Nixon's disasterous rules. Carter went top returned to the intrusive government courses, yet we envisioned that from a Democrat. We did no longer anticipate the extensive spending we've been given below Reagan. Spending below the Reagan administration broke all present archives on the time. And it isn't any longer straight forward to blame all of it on the democratic congress...he consistently had veto ability. Bush i replaced into even worse. The "kinder, gentler" conservative went returned on his promise to no longer improve taxes. it is the president who occupied the oval place of work because of fact the Berlin Wall replaced into tumbling down and he ought to no longer shop his interest...why? "...the financial gadget, stupid." That brings us to our final "small-government" Republican president. He have been given into place of work on a promise to start a huge spending spree on prescribed drugs. He endured the custom of me-tooing the Democrats: while the dems say they might furnish some form of government giveaway, he (and the Republican congress) say "me too." Economically conversing, we somewhat have 2 events to any extent further. Which celebration was for small government? In my lifetime, one consistently delivered platitudes approximately small government, the different had one president (Clinton) who declared that "the era of massive government is over," yet neither quite delivered a small government. we pick a potential third celebration.

Answer 10

not that i know of...the atom is the smallest known unit of matter
