How many isotopes does uranium-235 have?
three
The standard atomic weight of natural uranium is 238.02891(3). Naturally occurring uranium is composed of three major isotopes, uranium-238 (99.2739–99.2752\% natural abundance), uranium-235 (0.7198–0.7202\%), and uranium-234 (0.0050–0.0059\%)….List of isotopes.

What is the number of protons electrons and neutrons in 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.
How many neutrons does uranium have 235?
143 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.
Is uranium-235 an isotope?
This radioactive metal is unique in that one of its isotopes, uranium-235, is the only naturally occurring isotope capable of sustaining a nuclear fission reaction. (An isotope is a version of the element with a differing number of neutrons in its nucleus.)
What does the 235 mean in uranium-235?
Definition of uranium 235 : a light isotope of uranium of mass number 235 that constitutes less than one percent of natural uranium, that when bombarded with slow neutrons undergoes rapid fission into smaller atoms with the release of neutrons and energy, and that is used in nuclear reactors and atomic bombs.
What is the protons of uranium-235?
92
Uranium-235/Protons
How many protons does uranium-235 have?
92 protons
Uranium-235 has 92 protons.
What is the number of electron of uranium-235?
92 electrons
A neutrally charged atom of uranium-235 will have 92 electrons orbiting its nucleus.
Where do you find uranium-235?
Where does it come from? U-235 and U-238 occur naturally in nearly all rock, soil, and water. U-238 is the most abundant form in the environment. U-235 can be concentrated in a process called “enrichment,” making it suitable for use in nuclear reactors or weapons.
