You can't have that combination. Such an atom wouldn't be stable - not even for a tiny fraction of a second.The Atomic Mass is the sum of the atomic number (i.e., the number of protons), and the number of neutrons.
That's Manganese and it has (about) 30 neutrons - - - - BUT your question would have an answer of 11.
Only isotopes Fr-221 and Fr-223 are natural.
The atomic number is the number of protons in the nucleus of an atom, while the atomic mass is the total mass of the nucleus (both protons and neutrons)
The atomic strucutre and the sub-atomic particle. It place is according to how many shells it has and how many electrons in its outer shell. A new row on the table show a new shell on the element. The atomic number( the bottom) show the number of protons the neuclus has, and the atomic number(top one) shows how many protons and neutrons the atom has together this can be used to see if an isotope is made
Protons: 21 Neutrons: 29 Electrons: Normally 21
The atomic number of uranium is 92. The number of neutrons of the isotope uranium-235 is 143.
Uranium-237 has 142 neutrons. This can be determined by subtracting the atomic number (92) from the atomic mass (237) of uranium-237.
The most common isotope of uranium is uranium-238 with 146 neutrons.
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.
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).
Uranium 240 has 92 protons and electrons, but 148 neutrons because the atomic number is 92 and the atomic mass is 240.
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.
Uranium has many isotopes and each isotope has a different number of neutrons (N). N = atomic weight of the isotope - atomic number of uranium (A=92) The number of neutrons of the isotope 92U238 is 238-92=146 and the number of neutrons of the isotope 92U235 is 235-92=143.
All the isotopes of uranium contain 92 protons; the number of neutrons is variable for each isotope: Number of neutrons = Atomic weight of the given isotope - 92
The amount of neutrons can always be found by taking the atomic number from the mass number. Uranium has 146 neutrons. It depends on the isotope. See the link below for a list of uranium isotopes and how many neutrons are in each. You cannot tell how many neutrons it has with the given information. The most abundant isotope happens to be 238U, which has 146 neutrons.
There are 143 neutrons.
Because the atomic mass of this isotope is approx. 235 atomic units of mass.
