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.
Uranium -235 and uranium -238 are different of uranium?
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.
What is the difference between a synthetic emerald and a natural emerald?
Synthetic emeralds and natural emeralds are chemically the same, and their crystalline structure is the same. Only their origins differ.
Is uranium an isotope or neutral atom?
An atom has neutrons, protons, electrons. A chemical element has isotopes. With some exceptions isotopes has no name, but a number, equal to atomic mass.
Find out the names of two rocks that can be chemically weathered by natral rainwater?
I had the exact same question for one of my exams... I am fairly sure that the answer is: Granite and Limestone are two rocks that can be chemically weathered by natural rainwater. Hope I helped ! Alexx
Are the atomic bomb and depleted uranium the same weapon?
No, the atomic bomb and depleted uranium are not the same thing. Nuclear weapons are made with enriched uranium or with plutonium as the fissionable material. Depleted uranium is uranium that is "left over" after natural uranium is put through a process called enrichment to inprove the concentration of the isotope U-235 over that in natural uranium. The enriched uranium with its higher percentage of U-235 is fissionable, and it can be used in nuclear reactors and in nuclear weapons. Depleted uranium is used to make armor-piercing projectiles, and can be put through the neutron flux in an operating reactor to be transformed (transmuted) into plutonium.

What are the same between uranium and plutonium?
Both are chemical elements, solid, metals, radioactive, having fissile isotopes, chemically reactive, toxic etc.
Is plutonium and enriched uranium the same thing?
Plutonium and enriched uranium are different materials.Enriched uranium is uranium with a concentration of the isotope 235U greater than the natural concentration of 0,7 %.

Is a man made diamond as good as a wild diamond?
Man made diamonds are chemically the same as natural diamonds.

Are uranium plutonium and hydrogen dangerous?
1. Uranium is a possible polluting agent of the natural environment. 2. Uranium is a toxic and a radioactive chemical element. 3. Uranium release radium and radon. 4. Radioactive wastes are dangerous and need to be isolated. Plutonium: the same characteristics, but it is more toxic and radioactive. Hydrogen: it is a cause of severe explosions.
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.
Does the uranium contained in an atomic bomb get destroyed in the explosion or it is just transformed in another matter?
In a typical Little Boy gun bomb, like dropped on Hiroshima, about 1% to 5% of the uranium fissions into other elements lower on the periodic table. The rest of the uranium (as well as the depleted uranium in the tamper) is vaporized, reacts with oxygen in the air and drops out as uranium oxides in the fallout.In a typical Fatman implosion bomb, like dropped on Nagasaki, about 10% to 20% of the plutonium fissions into elements lower on the periodic table. The rest of the plutonium (as well as the depleted uranium in the tamper) is vaporized, reacts with oxygen in the air and drops out as plutonium oxides and uranium oxides in the fallout.A modern fission bomb might be able to fission 50% of its core fuel.Nothing gets destroyed, a small % of the tiny core transforms to other elements by fission, the bulk stays the same but is vaporized then oxidized then becomes part of the fallout.
What is one similarity between uranium 238 and carbon 14?
238U and 14C are radioactive isotopes of natural chemical elements.
