How sub atomic particles, i.e., electron, proton, neutron, etc are held in position?
831968
The nucleus is held together by the strong nuclear force.  It acts at extremely short distances.  It is strong enough to overcome the mutual repulsion of the protons.  The electrons orbit the nucleus, attracted to by the electric force.  Gravitation is much too weak to affect the relationships of subatomic particles within the atom.

Paint the protons one color, the neutrons another, and the electrons another. Put the nucleus together with the correct number of protons & neutrons. Put the correct # of electrons on it so that they appear to have some distance between them and the nucleus in an evenly spread manner. pretty simple. Styrofoam balls and toothpicks work great.

It looks like a stable atom. The protons, neutrons, and electrons are all equal so they do not need to take away from other atoms. The maxium number of protons, neutrons, and electrons vary for each element. For example some elements on the periodic table can only contain 8 protons on the outer shell. Etc. And this question would get better answer if it was in Physics or Chemistry.

Protons are positively charged hence have repulsion,so firstly you should wonder how come protons stay together happily in such a small nucleus.Answer:strong force:this is a force which is much more stronger than electrostatic repulsion,hence holds the nucleus together.Neutrons contribute towards this force without causing electrostatic repulsion hence are found in larger numbers in nucleus.

It will utilise quantum mechanics. At the subatomic level, matter behaves very differently to classical mechanics that we are familiar with in everyday life. The spin property of particles is not actually the particle spinning like a top, but is a term given to their angular momentum to help explain their interaction with each other.\n\nParticles can only spin in certain allowable directions, electrons have only 2 directions, other particles can have more. The ability to be in 2 spin states at once is due to uncertainty in that the particle could be in either state until it is observed and probability functions are used to describe its state.\n\nSimilarly a particle in a quantum well (a box with walls of electric potential) will move about with its energy in a fashion that can be described by its wave function. At any measurement it will be in a certain point (although with unknown momentum) but it will vary with every measurement.\n\nThese sorts of uncertainties are what are scientists are hoping to use in quantum mechanics. Calculations will actually be performed millions of times simultaneously providing varying results, but favourable probabilities will lead to the correct answer with immeasurably small innaccurary.\n\nPotential methods will utilise the spin magnetic moments of electrons, or the position of valence (outer) or free electrons moving between pairs of ions (charged atoms) accurately positioned in a semiconductor. There is still a lot of work required.

subatomic particles include the down, bottom, and strange quark with charges of -1/3 electron charge, the electron muon and tau lepton, and the sigma minus, the delta minus, and the omega minus.

The order of elements in the periodic table is determined by their atomic number, or number of protons (positively charged particles. The nucleus of the element is made up of protons and neutrons (neutral subatomic particles), and nearly all of the mass of the element resides here. \n\nElectrons "circle" the nucleus to even out the charge of the atom. The electrons organize themselves in layers, with a certain number of electrons in each layer. These layers are also referred to as the valence of the electron. The first layer has 2 electrons, the second and third have 8, the fourth has 18... These layers are what give the atom its volume.\n\nSince density is mass/volume, there isn't a linear relationship for density in each successive element, but the trend is density increases from left to right and top to bottom.

The atomic number is representative of the number of protons in the nucleus.  The atomic mass is representative of the number of total particles in the nucleus, which is made up solely of protons and neutrons.  That means that (35 total particles)-(17 protons)=18 neutrons.

Protons is the atom's atomic number.  It gives the atom its certain "chemical properties".  The proton has a weight of 1.  The neutron is a combination of a proton and electron roughly as evidenced by storing a neutron for more then 15 min and it will turn into a hydrogen atom.  For all intensive purposes the electron has no weight.  The neutron weighs 1 as well. When you combine the numbers of protons and neutrons in an atom you get the weight.  The neutrons act as glue for the atom and help keep it together.  Thus Uranium 235 is more unstable then Uranium 238. (235 is what they use in reactors).  The electron is attracted to the proton. Electron(-) proton (+).  But as you get towards the left section of the table you have atoms that want to lose their electrons since the want full orbitals.  As you get toward the right side of the table you get atoms that want to gain electrons to fill their shells.  These atoms that have a positive charge are known as cations longer word = positive. Shorter word or Ion = negative.

First, can a subatomic particle appear to be in two places at once?\n\nAccording to Quantum Theory, the answer is yes, because in order to know where a particle is, we have to measure its position, but the very act of measuring its position will alter the particle's behavior. So in effect we can never be sure where it is exactly. So in this sense, we may get measurements that give results that says the particle is here and there (this is the Uncertainty Principle).\n\nOf course, this is NOT new to quantum theory. So what's new? Someone mentioned "quantum entanglement" and "quantum teleportation". These are some of the new topics in quantum theory.\n\nPS - there is no such thing as Aether quantum dynamics or\n Auto dynamics, and Bohr's quantum mechanics is alive and well. The only addition we've added to Bohr's theory is the concept of electron cloud (i.e. a probability cloud) around the nucleus of an atom rather than electron orbits.

In biology?  Wow!  I would expect this in another category.  Atoms are the smallest particle into which an element can be divided.\n\nfor more information, see the site listed below:

An electron in an s orbital has zero angular momentum.\n\nViewed classically it is in Simple Harmonic Motion (SHM) passing through the nucleus of the atom.\n\nThe restoring force in the SHM is the electrical attraction between the electron and the positively charged nucleus.  The attraction is  an inverse square law which enables you to derive the equation of motion of the electron.\n\n  (Some "proton rich" isotopes undergo a type of radioactivity where this electron is captured by a proton in the nucleus which changes to a neutron which makes the atomic Number of the atom decrease by 1)

um  well its a sphere in the center. that contains 13 protons (atomic number is number of protons), and 14 neutrons (mass number - atomic number) and it has lil orbitals around it. basically circles. and on the closest one to the center, theres 2 lil electrons orbiting. on the 2nd from centre, theres 8 electrons orbiting. and on the next one, theres 3  (if 13 protons, then 13 electrons. cuz not charged) and then thatz it.

Protons and neutrons are made up of quarks, which are elementary partcicles (i.e have no inner structure that we know of). There are six different falvours of quarks: up, down, charm, strange, top and bottom. \nA proton is made of to up quarks and a down quark. A neutron is made up of two down quarks and an up quarks.\nElectrons are elementary partcicles that belong to a group called leptons.

Most micro-subatomic particles (i.e. Quarks, Muons, Leptons etc.) are, for the most part, the same size.  Some are a little larger than others are largly the same.  The smallest thing in existance however, is a string.  A string is not a particle though.
