The atomic weight of uranium is 238,02891(3) Atomic Mass units.
The mass number is the total number of nucleons (protons an neutrons) in the nucleus; the mass number is different for each isotope:
234U: mass number 234
235U: mass number 235
238U: mass number 238
What else can I help you with?
What is the mass number of urnanium?
Uranium is a non metal element. Atomic mass of it is 238.
What element has 235 mass number?
Uranium-235 is the element with a mass number of 235. It is a radioactive isotope of uranium that is used in nuclear reactors and nuclear weapons.
How do you find hyphen notation?
Hyphen Notation is the name of the element, then hyphen, then the mass number written after the element. For example, Chlorine-35.
How much is 1 molecule of uranium atoms?
Each isotope of an element has a different number of neutrons. Number of neutrons = Atomic mass of an isotope - atomic number of the element For uranium the atomic number is 92; for the isotopes see the list of isotopes with their atomic mass.
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.
What is the mass number of urnanium?
Uranium is a non metal element. Atomic mass of it is 238.
What element has 235 mass number?
Uranium-235 is the element with a mass number of 235. It is a radioactive isotope of uranium that is used in nuclear reactors and nuclear weapons.
What element has the atomic number 238?
There is NO element with the Atomic No. of 238. Atomic No. only go to ~ 110. However, There is an element with ATOMIC MASS of 238, it is an isotope of Uranium NB . Atomic Number refers to #1 the position in the periodic table #2 the number of protons in the element #3 the number of electrons in the neutrally charged element. Atmoic Mass refers to the Sum total of all the protons and neutrons in the nucleus of an element. An element such as Uranium would be shown in the periodic table as [238/92]U. The two numbers indicating the Atomic Mass and the Atomic Number.
How do you find hyphen notation?
Hyphen Notation is the name of the element, then hyphen, then the mass number written after the element. For example, Chlorine-35.
Which element has the heaviest atoms from the group calcium fluorine uranium?
Uranium has the heaviest atoms out of these three elements. It is a radioactive element with atomic number 92 and a relatively high atomic mass.
How much is 1 molecule of uranium atoms?
Each isotope of an element has a different number of neutrons. Number of neutrons = Atomic mass of an isotope - atomic number of the element For uranium the atomic number is 92; for the isotopes see the list of isotopes with their atomic mass.
What has the mass number of uranium-234?
The mass number of the isotope uranium-234 is 142.
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.
How much matter is in uranium?
In one mole of Uranium there are 238.02891g of Uranium. This number comes from its atomic weight on the Periodic Table. The mass of one mole of an element is its atomic weight in grams.
What is the mass number of uranium-235?
The atomic mass of uranium 238 is 238,050 788 247
What is the atomic number for uranium?
the atomic mass number for uranium is 92
The largest atomic mass?
The element with the largest atomic mass is oganesson, which has an atomic number of 118 and a standard atomic weight of approximately 294. This synthetic element is highly unstable and has a very short half-life, making it difficult to study.
