Answer:
1. The atomic number or proton number (symbol Z) of a chemical element and symbol A represents the atomic mass
13. The atomic number of uranium (see periodic table) is 92, and the mass number of the isotope is given as 238. Therefore, it has 92 protons, 92 electrons, and 238 — 92 : 146 neutrons. Its symbol is U92238 (or 238U).
C. The number of neutrons within the nucleus of a given atom can be found by subtracting the atomic number from the atomic mass. The mass number is the sum of protons and neutrons. To find the number of neutrons, subtract the atomic number, the number of protons, from the mass number.
D. Uranium (92U) is a naturally occurring radioactive element that has no stable isotope. It has two primordial isotopes, uranium-238 and uranium-235, that have long ... Other isotopes such as uranium-233 have been produced in breeder reactors. In addition ... Uranium-233 is made from thorium-232 by neutron bombardment
E. 92 protons
14. in alpha decay atomic mass is decreaed by afactor of 4 and atomic no by a factor of 2 while in beta decay atomic no is decreased by a factor of 1 and atomic mass by a factor of 2....so by solving completely your ans will be X6=atomic mass=226and atomic no 84
it was a little difficult for me to show you a complete sol sorry for that
but still i hope this ans can help you...
plz mark as brainliest if it helps in anyway..
