The number of neutrons equals the atomic weight minus the number of protons (238 - 92 = 146).Uranium has 92 protons, 92 electrons, and usually 147 neutrons, though another isotope has 143 neutrons.
The total number of protons and neutrons in an atom of uranium is known as its atomic mass number. For uranium, the most common isotope has an atomic mass number of 238, which indicates the sum of ...
The atomic number, Z, of any element, is the number of protons, positively charged nuclear particles, contained in the nucleus. The mass number (235) is the sum of the number of protons, AND the number of neutrons, NEUTRALLY charged nuclear particles. Note that only protons and neutrons contribute to atomic mass to any degree. You have 235U.
There are 238-92=146*"neutrons...." We are given that Z_"uranium"=92...because this is the number of protons, massive, positively charged particles present ion the uranium nucleus. Z="the atomic number" and it DEFINES the identity of the nucleus. The nucleus can also contain neutrons...massive, NEUTRALLY charged particles. Interactions between protons and neutrons result in the strong nuclear ...
The mass of uranium- 238 is 238 mass units. The total mass of an element is the sum of its protons and neutrons. There are 92 protons in this isotope, and its mass is 238, so that means that there are, 238 − 92 = 146 neutrons. See explanation. The mass number is 238, so the nucleus has 238 particles in total, including 92 protons.
146 Interestingly enough, the atomic mass of this isotope is given to you as a whole number. When this happens, you can say that the isotope's atomic mass is equal to its mass number. As you know, an isotope's mass number tells you how many protons and neutrons it contains in its nucleus. If you take Z to be the atomic number of the isotope, i.e. the number of protons it has in its nucleus ...
The number of neutrons equals the atomic weight minus the number of protons (238 - 92 = 146).Uranium has 92 protons, 92 electrons, and usually 147 neutrons, though another isotope has 143 neutrons ...
Well, for a start, the number of nuclear protons is #92#; i.e. for uranium, #Z,"the atomic number"=92# this is what defines uranium as an element. Now the mass number is #238#, and therefore there are #238-92=146* "neutrons"#. And finally the number of electrons, which is easy given what we know.
There are 143 neutrons. Uranium has the atomic number of 92 (the number of protons). The atomic mass of Uranium-235 is 235, the total of 235 protons and neutrons in the nucleus. Subtracting the ...
