The theory created to establish the existence of Subprotons uses mathematical symbols, but its inaccuracies, and inconsistencies, prevent us from any serious critique of it. In particular, monographs about the Subprotons do not suggest an elementary model for the st ...

... Hint: The molecular formula is an integral multiple of empirical formula. That is, the molar mass = empirical molar mass x integer. From C: H = 80.00/12 : 20.00/1 = 6.66: 20 = 1: 3. So the empirical formula is CH3 and the empirical molar mass of CH3 = 12x1+1x3 =15. So the integer = 30/15 = 2. Thus t ...

Atomic nucleus
The nucleus is the small, dense region consisting of protons and neutrons at the center of an atom. The atomic nucleus was discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment. After the discovery of the neutron in 1932, models for a nucleus composed of protons and neutrons were quickly developed by Dmitri Ivanenko and Werner Heisenberg. Almost all of the mass of an atom is located in the nucleus, with a very small contribution from the electron cloud. Protons and neutrons are bound together to form a nucleus by the nuclear force.The diameter of the nucleus is in the range of 6985175000000000000♠1.75 fm (6985175000000000000♠1.75×10−15 m) for hydrogen (the diameter of a single proton) to about 6986150000000000000♠15 fm for the heaviest atoms, such as uranium. These dimensions are much smaller than the diameter of the atom itself (nucleus + electron cloud), by a factor of about 23,000 (uranium) to about 145,000 (hydrogen).The branch of physics concerned with the study and understanding of the atomic nucleus, including its composition and the forces which bind it together, is called nuclear physics.
