How is the structure of an atom of uranium 235 different from the structure of an astom of uranium 238?
Uranium-235 has 143 neutrons, uranium-238 has146 neutrons.
Are uranium 235 and uranium 238 said to be radioactive molecules since they have the same number of protons but different numbers of neutrons?
No, Uranium-235 and uranium-238 are radioactive, natural isotopes (not molecules, but atoms) of the one and the same element: uranium.Both with 92 protons and 235-92 = 143 neutrons in U-235 but 146 neutrons in U-238.
How is the structure of an atom or uranium 235 dfferent to the structure of an atom of uranium 238?
Uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.
What are the half lives for uranium-235 and uranium-238?
703, 800,000
How is uranium 235 and uranium 238 similar?
Uranium-235 and uranium-238 are natural, radioactive isotopes of uranium; they have 92 protons and electrons but the number of neutrons is different: - for 235U: 143 - for 238U: 146
Uranium-235 and uranium-238 are different?
Uranium-235 and uranium-238 are different isotopes of the element uranium. They have different mass numbers due to different numbers of neutrons.
How is the structure of an atom of uranium 235 different from the structure of an astom of uranium 238?
Uranium-235 has 143 neutrons, uranium-238 has146 neutrons.
What are the similarities and differences between the isotopes uranium 235 and uranium 238?
Uranium-235 has 143 neutrons and uranium-238 has 146 neutrons. And of course the atomic masses are different.

Uranium 235 and Uranium 238 are said to be what kind of radioactivity?
Uranium 235 and uranium 238 are especially alpha particles emitters. They are natural radioactive isotopes.
What letter would a chemist use in front of 235 or 238?
U from uranium235U and 238U (recommended); also possible U-235 and U-238 or uranium-235 and uranium-238.
Does U-235 have fewer neutrons than common uranium?
Uranium-235 has 143 neutrons; uranium-238 has 146 neutrons. Each isotope has a different number of neutrons.
How much uranium-235 is typically found in uranium ore when it is mined from the ground?
Uranium-235 is found in nature at about 0.7% concentration to uranium-238.
What are the half lives for uranium-235 and uranium-238?
703, 800,000
Are there different types of uranium?
Uranium is a chemical element with three natural isotopes (234, 235, 238). The natural uranium has cca. 0,72 % uranium-235; uranium with a concentration of uranium-235 under 0,72 % is called depleted uranium; uranium with a concentration of uranium -235 above 0,72 % is called enriched uranium. Uranium in nuclear power and research reactors is used as metal, aloys, uranium dioxide, uranium carbides, uranium silicides, etc.
How is uranium 235 and uranium 238 similar?
Uranium-235 and uranium-238 are natural, radioactive isotopes of uranium; they have 92 protons and electrons but the number of neutrons is different: - for 235U: 143 - for 238U: 146
