Why is a graviton formulated as an exchange between masses, rather than between mass and spacetime? 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 order of magnitude of nuclear energy is 1MeV whereas the energy of atomic energy levels is of the order 1eV. The nucleus is surrounded by negatively charged particles called electrons which form a cloud around it. Necessary cookies are absolutely essential for the website to function properly.

The electronic configuration of C is (1s)2(2s)2(2p)2, and the atomic radius is 0.0914 nm. 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 "box" is provided by the confining electromagnetic force exerted by the nucleus on the electron. Having done this, a formula to measure the size of the nucleus was determined. Incredibly small. The positive charge of the nucleus comes from protons in it. The first orbital of H is represented by : = 1(a 01)3/2e r/a 0, where a 0 is Bohr's radius.

How to explain $E=mc^2$ mass defect in fission/fusion? 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? The number of protons and neutrons are called nucleons, and the mass of a nucleus is A time the mass of the nucleon (A is the number of nucleons in the atom). Size of atom is 104 times greater than size of nucleus. 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.
