How many electrons does a atomic weight 235?
Uranium 235 has several isotopes but, 235 would contain 235 electrons in one atom.
Which particles account for the difference between the atomic number and the mass number?
The answer is that it is neutrons that account for the difference between atomic weight and atomic number. The atomic number is the number of protons or the number of electrons in the atom, since they are normally equal. The atomic weightis the sum of the total number of protons, electrons AND neutrons in the atom. Knowing both the atomic number and the atomic weight of an atom lets you know the number of neutrons in the atom (the isotope). Example: Uranium, Atomic Number 92, Atomic Weight 235. The atomic number tell you that the uranium atom has 92 protons and 92 electrons. The atomic weight tells you that it has a combined total of 235 protons, electrons and neutrons. Since you know from the atomic number that there is a total of 184 protons and electrons in the atom (92 + 92) and from the atomic weight that the total number of protons, electons and neutrons is 235 (92 + 92 + X = 235), you now know that there are 151 neutrons in that uranium atom. The atomic number and atomic weight together tell you that the uranium atom 235 has 92 protons, 92 electons and 151 neutrons.
What is petroleum atomic number?
Petroleum is not an element, so it does not have an atomic number.
What does the 235 refer to in uranium 235?
235 is the approx. atomic mass of the isotope 235U.
What element was used in the atomic bomb dropped on Hiroshima?
Uranium-235 (U-235).
What equals 235?
This is the rounded atomic mass of the isotope uranium-235.
What is the atomic number and atomic mass of U-235?
i just asked you the question
What is the atomic number of uranium and how many neutrons does the isotope uranium-235 have?
The atomic number of uranium is 92. The number of neutrons of the isotope uranium-235 is 143.
How many neutrons does U-235 have?
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.
How many Electrons in uranium 235?
Because the atomic mass of this isotope is approx. 235 atomic units of mass.
What are the number of neutrons in an atom with mass number 235 and atomic number 92?
235-92 = 143
What 2 radioactive elements were chosen for the atomic bomb?
Uranium and Plutonium
