Uranium atomic number: 92
Uranium atomic weight: 238,02891
Uranium number of protons: 92
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
Because the atomic mass of this isotope is approx. 235 atomic units of mass.
The number of protons in neutrons in the nucleus of an atom is defined as atomic mass. The average atomic mass for all the isotopes of an element is given as the element's atomic weight. This is why atomic weights are decimal numbers.
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
Uranium 240 has 92 protons and electrons, but 148 neutrons because the atomic number is 92 and the atomic mass is 240.
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
Number of neutrons in an atomic nucleus = Atomic mass of an isotope - Number of protons in the nucleus For uranium the number of protons is 92; each isotope has of course a different mass.
All the isotopes of uranium have 92 protons and electrons.The number of neutrons is Mass number- Atomic number.
Uranium has 92 protons and electrons; the number of neutrons is different for each isotope: number of neutrons = atomic mass of an isotope - atomic number of uranium (92)
Uranium 235 has 92 protons and 92 electrons. To find the number of neutrons, follow this equation: Mass # - Atomic # = # of neutrons. Since the mass number of uranium 235 is 235 and has an atomic number of 92, the number of neutrons is 143.
Hi you also need the atomic number of Uranium which is always 92. Then the number of protons is 92 The number of electrons is 92 (if you want the Uranium atom) The number of neutrons is 236 - 82 which is 154.
The number of protons is equal to the number of electrons and the atomic number. The number of neutrons is different for each isotope (number of neutrons = atomic mass of the isotope [or mass number] - number of protons).
Because the atomic mass of this isotope is approx. 235 atomic units of mass.
The Atomic Mass or weight of an isotope of an element is the total number of protons and neutrons in its nucleus. The number of protons defines which element it is, this is called the atomic number. For uranium for example it is 92, but the atomic weight can be from 233 to 238, and these different versions of uranium are called isotopes. See Periodic Table for more details of all the elements. Add the no. of neutrons and the no. of protons to get the atomic mass.
The number of protons in neutrons in the nucleus of an atom is defined as atomic mass. The average atomic mass for all the isotopes of an element is given as the element's atomic weight. This is why atomic weights are decimal numbers.
92. All isotopes of Uranium have 92 protons. The number of protons in each element is represented by the atomic number of that element. Uranium is atomic # 92, so it will always have 92 protons. The difference in atomic mass (that's the 234 here) is due to difference in number of neutrons. Atomic mass is calculated (#of protons + # of neutrons), so Uranium-234 has 92 protons and 142 neutrons. Uranium-235 would have 92 protons and 143 neutrons and so forth. The number of protons contained in the nucleus of ANY atom will remain constant in ALL isotopes of the same element. Ex. Carbon-12 has 6 protons and 6 neutrons, Carbon-13 has 6 protons and 7 neutrons, etc. Carbon has an atomic number of 6. If the number of protons in the nucleus of an atom were different, it would no longer be the same element. Ex. Carbon - atomic #6 - has 6 protons with one more proton in the nucleus, it would have 7, and have atomic # 7.... then it would just be...... Nitrogen! Nitrogen - atomic #7 - has 7 protons
Uranium contain 92 electrons and protons. The number of neutrons is different for each isotope.Number of neutrons = Mass number - Atomic number
