No. All Uranium isotopes are called Uranium because they have 92 protons. The different isotopes (233, 235, 238, etc) all have 92 protons but have different numbers of neutrons in the nucleus. The chemical characteristics of an atom are determined by the number of protons in the nucleus which controls the number of electrons it takes to balance the atom and thus the chemical valence of the atom. When you get down to it, that is the reason why enrichment of Uranium is such a difficult task since there is only a three neutron difference in weight between fissionable U235 and non-fissionable U238 and no difference in chemical properties.


1 Uranium = 1 atom. U238 maintains 92 protons, 142 protons and 92 electrons.


This depends on a lot of things. When a neutron collides with an uranium atom, it might bounce off, cause the atom to decay, or be captured into the atom. But which it does depends on the isotope of the atom, the temperature of the atom, and the velocity of the neutron. My understanding is that it can cause any isotope of uranium to decay, and certainly it can bounce off any, but it can only be captured by U233, U234, or U235; the other isotopes of uranium, U236, and U238, will not capture neutrons. The interactions of various isotopes of different temperatures with neutrons of different velocities is complicated, and no simple rule about it can be stated.



one is carbon atom and the other is a uranium atom. simple.


Shortly, the difference between naturally occurring isotopes of uranium are specially physical (atomic mass, neutron numbers, decay type, half life, etc). Also, U-235 is a fissile material with thermal neutrons in classic nuclear reactors and U-238 is the fissile material in a breeder reactor. They have different amounts of neutrons- U238 has 3 more than U235 and the neutrons control the chemical reactions of the atom.


depends on the amount. Bryan's answer above is correct for the entire amount of an element that is present, but for an individual atom of an element, the answer is yes! Uranium, for instance, exists naturally as three different isotopes, U234, U235 and U238, the difference being the number of neutrons in the nucleas, and therefore, the atomic weights - 234, 235 and 238. In other words, a chunk of Uranium238 will weigh more than an equal sized chunk of 234.


The term half life describes the rate at which the isotopes of a particular atom decay. Thus, if you have a lump of Uranium 238 (U238), then the atoms in the lump will decay at the same rate as the half life. If that lump was created four billion years ago and it consisted of 100% U 238, today the lump would be half U238 and half something else, mostly lead. That would go for both the atoms and the whole lump. If the lump consisted of 10% U238 today it would consist of 5% U238, and 95% something else. The fact that the U238 has a half life of 4 billion years only affects the Uranium and nothing else.


The usual Carbon-12 is not radioactive. Uranium is radioactive. Radioactive means that the atom splits and spits out some energy or matter (with matter, the atom changes to another atom). Luckily, all the atoms don't split at once.


Uranium atom has seven electron shells.


The typical uranium atom is 238 times heavier than the typical hydrogen atom, although it should be noted that there are more than one isotope of both of these elements, so some variation in weight does exist. But uranium is tremendously heavier than hydrogen, for all isotopes.





The size of uranium atom depends on the number of electron around it


The empirical atomic radius of uranium atom is 175 pm.


Uranium-235 and uranium-238 has 92 protons and 92 electrons; but uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.


The uranium atom is electric neutral; uranium cations exist from 2+ to 6+.


Uranium is an atom with 92 protons and 92 electrons. They number of neutrons may vary, depending on the isotope of uranium.


The atom of uranium is electrically neutral.


See the link below to see an image of the uranium atom.


Each time a U235 atom decays, it emits 2-3 neutrons. The likelihood that one of these neutrons is captured by another U235 atom INCREASES with more mass. The SHAPE of this mass will also play a role, imagine a thin wire of U235, compared to a sphere, with regards to how likely a chain reaction will occur. Neutron reflection can also help redirect an errant neutron back into the mass so it can react instead. Compression (increase of density) plays a role as well.


Uranium atom has 92 protons and electrons; the number of neutrons is different for each isotope.


Copper atom has 29 electrons.Uranium atom has 92 electrons.


The normal uranium atom is neutral. Possible valencies of uranium are 2,3,4,5,6.
