How many neutrons does uranium 235 have?
143 neutrons
The nucleus of the U-235 atom comprises 92 protons and 143 neutrons (92 + 143 = 235).
How many electrons does uranium 235 have?
92 electrons
A neutrally charged atom of uranium-235 will have 92 electrons orbiting its nucleus.
Does uranium 235 emit neutrons?
Energy from the uranium atom The nucleus of the U-235 atom comprises 92 protons and 143 neutrons (92 + 143 = 235). When the nucleus of a U-235 atom captures a moving neutron it splits in two (fissions) and releases some energy in the form of heat, also two or three additional neutrons are thrown off.
How many protons electrons and neutrons are there in an atom of uranium 235?
The 235U(4+), for example, would contain 92 – 4 = 88 electrons. Find the number of neutrons in the isotope by subtracting the number of protons from the mass number given in the symbol. For example, 235U, which contains 92 protons, therefore contains 235 – 92 = 143 neutrons.
What is the protons of uranium 235?
92
Uranium-235/Protons
The isotope of uranium of greatest importance in atomic bombs, U-235, though, has three fewer neutrons. Thus, it also has an atomic number of 92 (since the number of protons has not changed) but an atomic weight of 235 (92 protons plus only 143 neutrons).
What is the formula for uranium 235?
Uranium-235 Symbol The symbol or formula for this radioactive isotope is 235U. It is also denoted by U-235.
How do you find the mass of uranium 235?
Calculate the binding energy of uranium-235 (92U235), if its atomic mass is 235.043943 a.m.u. (92) (1.007825 a.m.u.) + (143) (1.008665 a.m.u.) = 236.958995 a.m.u. The binding energy per nucleon is therefore 1782.9/235 = 7.59 MeV/nucleon. This number is also shown in Figure 12-4.
What is the mass number of uranium-235?

What element has 10 neutrons?
Each neon atom has 10 protons. There are three stable isotopes of the element, with atoms having 10 neutrons (neon-20), 11 neutrons (neon-21), and 12 neutrons (neon-22).
What element has 49 electrons?
Indium has 49 electrons, with an electronic configuration of [Kr]4d 105s 25p 1. In compounds, indium most commonly donates the three outermost electrons to become indium(III), In 3+.
How many protons neutrons and electrons does uranium have?
Uranium has an atomic number of 92 which means there are 92 protons and 92 electrons in the atomic structure. U-238 has 146 neutrons in the nucleus, but the number of neutrons can vary from 141 to 146.
What is the atomic number of uranium 235?
The symbol for uranium-235 is U, its atomic number is 92, and the mass number is 235.
