What is the number of neutrons uranium?
The number of neutrons in the nucleus of an atom varies. Let's look at the issues.
First, hydrogen is an "odd bird" in the periodic table. It is far and away the most common element in the universe, but most of it (over 99.98% !) has on a lone proton for a nucleus. A tiny bit has one neutron, and an even smaller bit has two neutrons. That said, let's look at the "general population" of the periodic table.
Lighter elements have about a one-to-one ratio of neutrons to protons. This ratio creeps up as we move up the periodic table, and it is over two to one (neutrons to protons) at the upper end of the table. Each element has a number of different isotopes, and each isotope has a different number of neutrons in its nucleus. The bottom line is that each isotope of each element will have to be considered individually to determine the number of neutrons in its nucleus.
What are the benefits of using uranium?
Uranium is primarily used in nuclear power plants to generate electricity. It is a highly efficient fuel source that produces large amounts of energy compared to other fuels. Additionally, uranium has the potential to reduce greenhouse gas emissions and lessen dependence on fossil fuels for energy production.
Are trans uranium elements synthetic?
Yes. Plutonium (atomic number: 84) is a trans-uranium element (meaning it has a higher atomic number than uranium (82)). Every element on the periodic table after uranium is man-made.
Uranium is an Alpha emitter, ingestion of uranium containing materials exposes the body internally to Alpha radiation which can mutate cells causing cancer.
Uranium is also a moderately toxic heavy metal, ingestion of very large amounts could cause heavy metal poisoning.
Uranium should be stored in a secure, dry, and well-ventilated area to prevent any leakages or contamination. Proper labeling and training for handling uranium are also essential to ensure safety. Additionally, it's important to comply with regulations and guidelines for storing radioactive materials.
How dangerous is uranium mining?
The radioactivity of natural uranium is not so important. The external irradiation is very low.
But the internal irradiation is dangerous: alpha radiations from inhaled uranium, radium and radon (Ra and Rn released by decay from U) can destroy pulmonary alveoli and cause lung cancers.
Also the ingestion is dangerous because soluble salts of uranium are toxic.
When was uranium dating first used?
Uranium dating, also known as radiometric dating, was first used in the early 20th century, around the 1920s. It has since become a widely used method to determine the age of rocks and materials on Earth.
Is uranium in the lanthanide family?
cerium is atomic number 58 element and is in lanthanoide family and is a transition metal
Uranium is typically measured in units of weight such as grams or kilograms. For radioactive purposes, activity is measured in becquerels (Bq) or curies. In industrial applications, uranium content may also be measured in percentage by weight.
How do elements that follow uranium produce?
They're produced in a nuclear reactor. Basically atoms of one element are bombarded with other smaller atoms. The idea is to make them stick together to form a heavier atom. So theorectically take Uranium say U 238/92 and bombard with Carbon say C 12/6 and you hope to make Californium Cf 250/98. That is a very simplified explanation. An online search may reveal more information.
What was the chemical element uranium named after what planet?
It was the other way round. Uranium was named after a planet. That planet was Uranus.
What is the atomic number of uranium?
The atomic number of uranium (U) is 92. The atomic weight of U is 238.02891(3) grams per mole.

Benefits of uranium mining in Saskatchewan?
Applications of uranium:
- nuclear fuel for nuclear power reactors
- explosive for nuclear weapons
- material for armors and projectiles
- catalyst
- additive for glass and ceramics (to obtain beautiful green or yellow colors)
- toner in photography
- mordant for textiles
- shielding material (depleted uranium)
- ballast
- and other minor applications
Also a mine or plant need workers and the unemployement will be lower.

How many Electrons in uranium 235?
Because the atomic mass of this isotope is approx. 235 atomic units of mass.
Is solar energy contained in uranium?
No, solar energy is derived from the sun's radiation, while uranium is a radioactive element used in nuclear power plants to generate electricity through a process called nuclear fission. Solar energy and uranium are distinct sources of energy with different origins and methods of generation.
What are the masses of uranium and in uranium oxide?
The percentage of uranium in uranium dioxide is 88,149.
How is uranium 235 different from uranium 231?
Uranium-235 is a natural isotope with 143 neutrons.
Uranium-231 is an artificial isotope with 139 neutrons.
Where can fossil fuels be used?
Fossil fuels are used in thermal power stations for production of electricity. They are used as automobile fuels i.e petroleum. They are used in factories and industries as power source like in Iron or Steel industries.
How did the Holocaust gets its name?
The Holocaust refers to the murder of about 6 million Jews by the Nazis in World War 2. Sometimes other victims of Nazi mass killings are also included, in which case the total number of victims is much higher than 6 million.
The term The Holocaust in this specific sense has been in widespread use since the late 1970s. Before that it was referred to as the Final Solution [of the Jewish Question]. This was not a very satisfactory term as it was a translation of the Nazis' own term for the genocide.
The word holocaust (with a small h and without The) means: 1. great destruction, especially by fire; 2. whole burnt offering.Because of the religious connotations of the word, some people prefer to use the word Shoah (Hebrew for great calamity, disaster).
In addition to the Jews, the Nazi killed many other groups. Some people include these other groups, some don't.
The modern, specific sense of Holocaust was popularized by Elie Wiesel from the late 1950s onwards.

There are thought to be about 5 million tons of the grade of ore being mined now, typically 0.1 to 0.25 percent uranium oxide. So that represents 5000 to 12500 tons of uranium. This will keep the industry going for some years yet. Eventually lower grade ores will have to be mined which will be more expensive, but there is no reason to expect a shortage.
What size of nuclear bomb made with one ton of uranium?
Its really hard to say, the only nuclear bomb that might contain that much uranium (probably as depleted uranium) would be a hydrogen fusion bomb with a uranium tamper.
Depending on many design features, it would probably weigh a bit under 2 tons and have a yield somewhere between 2 megatons and 20 megatons, most of that produced by fission of the uranium tamper.
NO nuclear bomb could ever contain that much weapons grade uranium, as it would be so far beyond critical that it would simply melt in the factory as it was being assembled and kill anyone nearby with neutron and gamma radiation.
