How many neutrons are there in an atom of uranium whose mass number is 235?

Like all isotopes of uranium (identified by the "mass number" following the element name--235, in this case), U 235 has the atomic number 92. An element name is really just a more memorable way to designate a specific atomic number. This is because different isotopes with the same atomic number such as U 238 (the common type) and U 235 (a rare type)--or, to take a more common example, Carbon 12 (the common kind) and the slightly radioactive Carbon 14 (extremely rare), share the same number of electrons with all weights of the element. To put it another way, an isotope identified by a mass number (235 or 238) is just a slightly leaner or heavier version of the same atomic number. So, even though U 238 has three more neutrons in its nucleus than does U 235, the two have the same atomic number; which is just another way of saying they are the same element. The number of electrons determines how an element behaves chemically and that's how element names are assigned.
Elements are sorted by chemical interaction characteristics, not by weight: weight. The mass number (in this question, 235) is a subdivision of element/atomic number. If an element has the same name, but a different mass number, all elements with that name share the same atomic number.

What is a uranium atom?
Uranium atom has 92 protons and electrons; the number of neutrons is different for each isotope.
How is the structure of an atom or uranium 235 dfferent to the structure of an atom of uranium 238?
Uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.
How many neutrons are in the isotope uranium-238?
Uranium, atomic number 92, has several isotopes, and 238U is just one of them. Remember that a nucleon is one of the particles that make up the nucleus of an atom, and that means a proton or a neutron. In the case of this isotope of uranium, it has the 92 protons we'd expect for uranium, and it has 146 neutrons in its nucleus along with those protons. That's 238 necleons in the nucleus if 238U. Wikipedia has more information on uranium and on the nucleon, and links are provided.
How many neutrons are in a normal uranium atom?
Uranium has 92 electrons and protons.Uranium-234 has 142 neutrons, uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.
How many protons and neutrons are in uranium-241?
Uranium is the 92nd element on the periodic table. That means there are 92 protons in 1 uranium atom, no matter which isotope. Protons are constant through an element. Every single atom of Uranium has 92 protons. Neutrons, however change with isotopes. 241 is the number of protons and neutrons together. So subtract 92 from 241 to get the number of neutrons in uranium 241

What is the uranium atom?
Uranium is an atom with 92 protons and 92 electrons. They number of neutrons may vary, depending on the isotope of uranium.
If uranium has an atomic number of 92 how many protons and neutrons are found in the uranium 238 atom?
Uranium 238 has 92 protons and 146 neutrons.
What is the original atom of uranium?
Uranium neutral atom has 92 protons and electrons; the number of neutrons is different for each isotope.
How is the structure of an atom or uranium 235 dfferent to the structure of an atom of uranium 238?
Uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.
How many neutrons are in the isotope uranium-238?
Uranium, atomic number 92, has several isotopes, and 238U is just one of them. Remember that a nucleon is one of the particles that make up the nucleus of an atom, and that means a proton or a neutron. In the case of this isotope of uranium, it has the 92 protons we'd expect for uranium, and it has 146 neutrons in its nucleus along with those protons. That's 238 necleons in the nucleus if 238U.

How many protons and neutrons are in uranium-241?
Uranium is the 92nd element on the periodic table. That means there are 92 protons in 1 uranium atom, no matter which isotope. Protons are constant through an element. Every single atom of Uranium has 92 protons. Neutrons, however change with isotopes. 241 is the number of protons and neutrons together. So subtract 92 from 241 to get the number of neutrons in uranium 241
Why is uranium the heaviest atom?
Uranium is a heavy chemical element, but not the heaviest; the aspect is due to a greater number of protons and neutrons.
How many particles are found in the nucleus of a uranium atom?
how many particles are found in the nucleus of a uranium atom? 92 protons and x neutrons; the number of the neutrons is dependent of the isotope atomic mass. Also 92 electrons.
If uranium atomic number is 92 and it has 10 neutrons how many?
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.
Calculate the number of neutrons of the atom whose atomic number is 42 and whose mass number is 96?
No. of neutrons= Mass no.- No.of protons(atomic no) therefore, no. of neutrons =96-42 = 54
