How many protons, neutrons and electrons does Sodium  have?
820564
Sodium has an Atomic Number of 11 and an Mass Number of 23 \n\nThis means an atom of Sodium has 11 Protons and therefore 11 electrons. \n\nSince the number of Protons + Neutrons is 23 and there are 11 Protons there must be 12 Neutrons

Neutrons do not have atoms, in fact they are particles that make up the nuclei of atoms along with protons.

Silicon's elemental number is 14, meaning it has 14 protons. If the atomic weight is 28, then subtracting 14 (the mass of the protons) gives you the solution, 14 neutrons.\n\nAtomic mass = mass of protons + mass of neutrons + a tiny bit of mass from electrons.\n\nProtons and neutrons have nearly the same mass, and electrons have hardly any mass at all.

In a stable atom, not an ion, the # of electrons equals the # of protons, so potassium would have 19 protons, and 19 electrons.  Protons and Neutrons make up the atomic weight of the atom, so you take the atomic weight and subtract the atomic # and you are left with # of neutrons.  39.0938-19=20 because you round, you can't have a fraction of a neutron.  Therefore, there are 20 neutrons, 19 electrons, and 19 protons.

Atoms are combinations of protons and neutrons with electrons flying around. They form the basic "elements" of matter.\n\nThe nucleus of an atom has protons and neutrons (except for hydrogen which has one proton). There are about the same number of protons and neutrons in each nucleus, although for larger nuclei (like uranium) there are more neutrons.\n\nAll of these particles have a variety of specific characteristics. For example an electron has a negative charge and a proton has a positive charge, while the neutron is neutral. The charge of the proton and electron are identical except for the sign.\n\nProtons and neutrons are both made of quarks. A proton has two "up" quarks and one "down" quark, while the neutron has two "down" quarks and one "up" quark. (The up and down are just names for these two types of quark, there is no physical significance to the name. They could have selected \nChocolate and Vanilla instead.)\n\nProtons and neutrons are almost always described as being composed of three quarks, but there are also gluons running around. Gluons are the particles which control the interaction of quarks within a proton or neutron. They carry the force that binds the three quarks together to form the larger particle.\n\nSo a proton or neutron has three quarks and a cloud of gluons.\n\n(Just as an aside: If one combines a proton and an electron and a neutrino you will get a neutron, but, in the oddness of quantum physics that doesn't mean a neutron is made of these little guys.)\n\nElectrons on the other hand seem to have no consituents, at least down to the level that has been probed with modern instruments.

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.

Copper is #29 on the period table (yes, 4th period), but notice it's average atomic mass is 63.55.  Since electrons weight practically nothing, that means the weight of the protons and neutrons is 63.55.  Since it is #29, it has 29 protons by definition.  So on average it has 63.55 - 29 = 34.55 neutrons.\n\nRemember that though an element has roughly the same number of neutrons as protons, each atom can have a different number of neutrons.  These are called "isotopes".  But on average, copper has 34.55, according to the periodic table I've cited below.

First the answer 129p and 130n is incorrect.  There is no element 129 and if there were it would certainly have more than 130 neutrons.  I think you are missing a piece of information, that being the atomic number or identity of the element. There are a number of elements that have an isotope that has a mass number of 259.  The 259 is the number of neutrons plus protons.  If you know the identity of the element, then you know number of protons (atomic number) and you can calculate the number of neutrons.  For example, if the isotope is No-259 then Nobelium has 102 protons and isotope would have 259-102 = 157 neutrons.  The number of electrons in an atom is equal to the number of protons.

Potassium (chemical symbol K) has 19 each of protons and electrons, because it has an atomic number of 19.  Potassium has more than one naturally occuring isotope.  Potassium can have an atomic mass of 39, 40, or 41.  However, over 90% of naturally occuring Potassium is K-39, with 20 neutrons.  K-41, with 22 neutrons, is also stable.  K-40 has 21 neutrons, and does occur in nature, but with an abundance of only 0.012%.  In addition, it is not truly stable, although its half-life is over a billion years.

Not only sodium rather all elements of s and p orbitals with 1 or 2 valency do not exist as naturally found pure elements.\n\nThis is because of their very high reactivity with majority of substances present in the atmosphere, sea and earth crust.

Na is larger than Na+.\nF is larger than F+.\nCations are always smaller than the parent atom as the effective nuclear charge acting on an electron increases as the total number of electrons decreases.\nIn the case of Na&Na+,Na+ has one whole shell lesser than Na.

sodium ions are one short in electrons than the sodium atoms while number of protons remain the same .Hence the nucleus exerts extra attractive force on the electrons resulting in the shrinking of the size of the ion.
