A neutrally charged atom of uranium-235 will have 92 electrons orbiting its nucleus.
What is the number of electrons and neutrons for uranium?
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. Because uranium is radioactive, it is constantly emitting particles and changing into other elements.

How many electrons does uranium-239 have?
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.
How many neutrons does uranium-235 have?
143 neutrons Energy from the uranium atom The nucleus of the U-235 atom comprises 92 protons and 143 neutrons (92 + 143 = 235).
Can an atom have no electrons?
In the periodic table. The term "neutronium" was coined in 1926 by Andreas von Antropoff for a conjectured form of matter made up of neutrons with no protons or electrons, which he placed as the chemical element of atomic number zero at the head of his new version of the periodic table.
How many electrons does uranium-234 have?
What is the number of electrons in uranium 234? This means U has 92 protons as a neutral element therefore it has 92 electrons. The answer is 92 protons 142 neutrons 92 electrons.
What is the difference between uranium-238 and uranium 236?
The nucleus of the U-235 atom contains 92 protons and 143 neutrons, giving an atomic mass of 235 units. The U-238 nucleus also has 92 protons but has 146 neutrons – three more than U-235 – and therefore has a mass of 238 units.
What’s the difference between uranium-235 and uranium-238?
The difference between the three isotopes is the number of neutrons present in the nucleus. U-238 has 4 more neutrons than U-234 and three more neutrons than U-235. U-238 is more stable thus being more abundant naturally. U-235 is used as fuel in nuclear reactors and/or weapons.
How do you find the number of electrons?
The number of electrons in a neutral atom is equal to the number of protons. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

Particles that are smaller than the atom are called subatomic particles. The three main subatomic particles that form an atom are protons, neutrons, and electrons.
How many atoms are in the world?
According to the US Department of Energy's Jefferson Lab, the answer is: 133,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000.
Why is uranium-235 better than uranium-238?
Therefore U-235 is slightly less bound than U-238 and therefore breaks up more easily than U-238. Both isotopes can be used in preparation of atomic bomb. U-235 can be used directly while U-238 is first converted to Pu-239 by neutron reaction.
How many protons does uranium-235 have?
92 protons In the nucleus of each atom of uranium-235 (U-235) are 92 protons and 143 neutrons, for a total of 235. The arrangement of particles within uranium-235 is somewhat unstable and the nucleus can disintegrate if it is excited by an outside source.
