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
Atomic mass number = Number of protons + Number of neutrons Number of protons of uranium nucleus is 92. The number of neutrons is different for each isotope. Example for 238U: 92 protons + 146 neutrons = 238
Uranium atomic number: 92 Uranium atomic weight: 238,02891 Uranium number of protons: 92
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.
Atomic weight (not mass) of uranium is 238,02891.
The atomic weight of uranium is 238,02891.
Atomic number of uranium: 92 Atomic weight of uranium: 238,02891
The atomic weight (not mass) of uranium is 238,02891(3).
Uranium has the greatest atomic weight (238,02891 a) between the natural elements.
The atomic weight of uranium (not mass) is 238,02891.
Atomic mass number = Number of protons + Number of neutrons Number of protons of uranium nucleus is 92. The number of neutrons is different for each isotope. Example for 238U: 92 protons + 146 neutrons = 238
Uranium atomic number: 92 Uranium atomic weight: 238,02891 Uranium number of protons: 92
The atomic weight of uranium is 238,02891(3); the word weight is correct here not mass.
The atomic weight of uranium is 238,02891.
The atomic weight of uranium is 238,02891(3) atomic mass units.
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.
Atomic weight (not mass) of uranium is 238,02891.
The atomic weight of uranium is 238,02891.
