Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom. About 5 million hydrogen atoms could fit into a pin head. The formula to measure the size of nucleus is: R = R0A1/3 Where R0 = 1.2 * 10-15 m Density of Nuclear Matter The density of a nucleus () is its mass divided by the total volume. An atom approximately an angstrom in size, 0.1 nanometer, or 1 x 10^-10m The size of the universe is rather more difficult to define. [a] R = R 0 A 1 3 Where R 0 = 1.210 -15 m. From the formula, we can conclude that the volume of the nucleus, which is proportional to R 3, is proportional to A (mass number). I don't know of any better model, although I'm not an expert in nuclear physics so I can't be sure one doesn't exist.

In the formula you provide, the mass $m_a$ that appears really refers just to the mass of the particle in the box, which for the atom is the electron. The bismuth nucleus with 83 protons and 126 neutrons is the largest stable nucleus. So the way I approached this was to consider $$\frac{E_a}{E_n}=10^{-6}\Rightarrow \frac{\frac{h^2}{8m_aL_a^2}}{\frac{h^2}{8m_nL_n^2}}=\frac{m_nL_n^2}{m_aL_a^2}=10^{-6}\Rightarrow \frac{L_a}{L_n}=\sqrt{10^6\cdot m_n/m_a }.$$The mass of the nucleus we assume to be 1u but what about the mass of the atom? Shouldn't the mass of a typical atom also include the mass of the nucleus, along with the mass of the electron? Which is almost equal to around 1015 m of the size of the atom.

In the formula you provide, the mass $m_a$ that appears really refers just to the mass of the particle in the box, which for the atom is the electron. about 10-15 m The masses of other atoms go up to about 200 times this. This means that the nucleus has a diameter 10,000 times smaller than the atom. The neutron count of a nucleus determines which isotope of an element is that atom. This mass of a proton is considered as unit mass (1 a.m.u.). The mass of the box itself does not affect the energy of the particle inside it: the only thing that matters is the length of the box. The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom. The centre of an atom is positively charged, and almost all of an atoms mass is contained in the central part called the nucleus. It might be so large as to not be able to be measured because it is impossible to traverse it in the time that the universe will exist! The difference in the number of neutrons of these isotopes gives them different atomic masses. What is the order of magnitude of the diameter of a typical atom? Was this answer helpful?

A big part of what they do at Jefferson laboratory is to search for the change between nucleon--meson degrees of freedom (as reasonably well described by quantum hadrondynamics) and quark--gluon degrees of freedom (as described by quantum chromodynamics); but even the on-set of QCD dominated behavior does not correspond to quark--gluon plasma which occurs at much higher energies. Another thing to be noticed in the equation is that there is no mention of density in the equation.

Error bars are shown for all data and represent statistics plus point-to-point systematics (but not not systematics that would shift all the data for a single nucleus). These dimensions are much smaller than the diameter of the atom itself (nucleus + electron cloud), by a factor of about 26,634 (uranium atomic radius is about 156 pm ( 156 1012 m )) [9] to about 60,250 ( hydrogen atomic radius is about 52.92 pm ).

Answer (1 of 4): For the hydrogen atom, if the nucleus were the size of the sun, the actual atom size (Bohr Radius) would extend about 6 times farther than the distance to Pluto. Rutherford wanted a very thin sheet for his experiment, and gold foil could be pounded into sheets of only 0.00004 cm thickness. But the answer in the book uses that $m_e = m_a$ so that the mass of the nucleus is much greater than the mass of the atom. A good comparison of the nucleus to the atom is like a pea in the middle of a racetrack. University of Illinois at Urbana-Champaign, Volume measurement of irregularly shaped objects. J.J.
