Uranium-235 and uranium-238 are isotopes of uranium, meaning they have the same number of protons but different numbers of neutrons. Uranium-235 is used in nuclear reactors and weapons due to its ability to sustain a nuclear chain reaction, while uranium-238 is more abundant in nature but less useful for these purposes.

Are uranium 235 and uranium 238 said to be radioactive molecules since they have the same number of protons but different numbers of neutrons?
Uranium-235 and uranium-238 are not considered molecules, they are isotopes of uranium. Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons. Both uranium-235 and uranium-238 are radioactive isotopes, meaning they spontaneously decay and emit radiation.
How is the structure of an atom or uranium 235 dfferent to the structure of an atom of uranium 238?
The main difference between uranium-235 and uranium-238 is their atomic masses. Uranium-235 has 235 atomic mass units (AMU) while uranium-238 has 238 AMU. This difference in mass is due to the number of neutrons in the nucleus of each isotope.
How is the structure of an atom of uranium 235 different from the structure of an astom of uranium 238?
The main difference is in the number of neutrons present in the nucleus. Uranium-235 has 143 neutrons, while uranium-238 has 146 neutrons. This leads to differences in their relative abundance and stability.
Write the full atomic symbols for uranium 235 and 238?
The full atomic symbols for uranium are: Uranium-235: ^235U Uranium-238: ^238U
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.

What are the similarities and differences between the isotopes uranium 235 and uranium 238?
Similarities: Both uranium-235 and uranium-238 are isotopes of uranium, meaning they have the same number of protons but different numbers of neutrons. They are both radioactive and can undergo nuclear fission. Differences: Uranium-235 is the primary isotope used for nuclear fuel and weapons due to its higher susceptibility to fission compared to uranium-238. Uranium-238 is more abundant in nature, constituting over 99% of natural uranium, while uranium-235 is less common.

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?
A chemist would use the letter "U" in front of 235 or 238 to represent uranium isotopes 235 and 238.
Write the full atomic symbols for uranium 235 and 238?
The full atomic symbols for uranium are: Uranium-235: ^235U Uranium-238: ^238U
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.
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.
What are the similarities and differences between the isotopes uranium-235 and uranium-238?
Both uranium-235 and uranium-238 are isotopes of uranium, with the same chemical properties but different atomic masses. The main difference is that uranium-235, a fissile isotope, is used in nuclear reactors and weapons due to its ability to sustain a nuclear chain reaction, while uranium-238 is not fissile. Both isotopes are radioactive and decay over time, with uranium-238 having a longer half-life compared to uranium-235.
