IMAGES An atom consists of a positively charged nucleussurrounded by one or more negatively chargedparticles called electrons. In it, I explained the structure and radioactivity of Technetium and Radon. And with solution plz, 17. The unstable nucleus of uranium-236 can be regarded as a uniformly charged sphere of charge Q = + 92 e and radius R = 7.4 × 10 − 15 m. In nuclear fission, this can divide into two smaller nuclei, each with half the charge and half the volume of the original uranium-236 nucleus. The nucleus of the uranium atom contains 92 protons. Thus, we use subtraction to identify the isotope of the thorium atom—in this case, \(\ce{^{231}_{90}Th}\). Density of Uranium. Themass of the climber is 60 kg and her water bottle has a mass of 500 gm .I if the bottle starts from rest, how fast is it travelling by the time it reaches the bottom of the slope? The heaviest natural element is Uranium-238, which contains 92 protons for 146 neutrons. The nucleus (plural, nuclei) is defined as the dense, central part of an atom, consisting of two subatomic particles, namely protons and neutrons. Density of Uranium is 19.05g/cm 3. We can see below that uranium-238 still has 92 protons but it now has 146 neutrons so its nucleon number is now 238. Its nucleus is so full of protons and neutrons that it draws its core electron shells in close. Its radius of this nucleus will be: After decay, the daughter nucleus is Ni, which has Z = 28, and there is an electron, so that the total charge is also 28 + (–1) or 27. These two nuclei will repel each other and should gain a total kinetic energy of c. 200 Mev., as calculated from nuclear radius and charge. The copper atom has a number 29 in Mendeleyev's periodic table of elements. Each proton has a positive charge of 1.6*10-19 C.

So the answer is +92x1.6x10^-19=+1.5x10^-17C. Another 8.8 MeV escapes the reactor as anti-neutrinos. It is about 2.0 for the spontaneous fission of uranium-238 and 4.0 for that of fermium-257. Uranium-235 (235 U) is an isotope of uranium making up about 0.72% of natural uranium.Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a fission chain reaction.It is the only fissile isotope that exists in nature as a primordial nuclide. The nuclei of large atoms, such as uranium, with 92 protons, can be modeled as spherically symmetric spheres of charge. Given that protons and neutrons Charge of the nucleus=atomic mass (ie no of protons )×(+e) Where +e=1.6×10^-19 C (i) Explain what is meant by isotopes. A neutral atom contains equal numbers of protons and electrons. Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus.They are generally produced in the process of alpha decay, but may also be produced in other ways.Alpha particles are named after the first letter in the Greek alphabet, α.The symbol for the alpha particle is α or α 2+. So if you move on to part A so envision it pits two nuclei of equal radios are so therefore we can come up with an expression for the radio. Charge of alpha particle and uranium nucleus is ...
