What did Becquerel discovered from uranium?
He found that uranium is radioactive. Uranium is in the f block. Atomic number of it is 92.
Where are most synthetic elements found on periodic table?
These elements are found after uranium.
How you calculate the relative atomic weight of uranium?
The atomic weight of an element is derived from the atomic masses of the isotopes of this element and from the percentage of these isotopes. The correct terms are: - atomic weight for elements - atomic mass for an isotope
What is the physical state of Uranium?
Uranium is a natural chemical element, metal, solid.The atomic number is 92 and the atomic weight is 238,02891(3).
Is uranium a compound or a mixture?
Uranium is a metallic element. It is a pure element and nether a compound nor a mixture. Uranium has the symbol U and number 92 on the periodic table. It is used by the military to make anti armour piercing munitions. It is also used in nuclear power stations. Uranium is an element. Its atomic symbol is U, atomic number is 92, and it has an atomic mass of 238.0 In nuclear reactors, however, only certain isotopes are used which are not found naturally. The uranium found naturally must be "enriched."
How is the atomic weight of an element found?
you add the number of protons (the atomic number) to the number of neutrons
If uranium has an atomic number of 92 how many protons and neutrons are found in the uranium 238 atom?
In a uranium-238 atom, the number in the isotope name stands for the total number of protons and neutrons in the nucleus. So in this case, uranium-238 has 92 protons (atomic number) and 146 neutrons (238 - 92).
Which natural non-synthetic element has the highest atomic number on the periodic table?
The element with the highest atomic number on the periodic table is uranium. It has an atomic number of 92 and is a naturally occurring element found in small amounts in the Earth's crust.
What is the difference between a carbon atom and a uranium atom?
I won't even waste the time looking up actual numbers.a mole of atoms of helium is about 4 grams, therefor 1 gram of helium is about 0.25 moles of helium atomsa mole of atoms of uranium is about 238 grams, therefor 1 gram of uranium is about 0.0042 moles of uranium atomsA gram of helium contains more atoms than a gram of uranium by about a factor of 60.
Which heavy metal is found in nuclear power stations?
Uranium is the heavy metal found in nuclear power stations. Uranium has the atomic number of 92, and it has many applications in nuclear technology. A very common isotope of uranium is uranium-238.
What element has atomic number 93?
The element with atomic number 93 is neptunium. It is a radioactive actinide metal that is commonly found in trace amounts in uranium ores.
The number of neutrons in an atom can be found by subtracting the atomic number from the?
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
