No. By definition isotopes of an element have the same number of protons (that is what makes them uranium, for example) but different numbers of neutrons (neutral particules in the nucleus which provide mass).
No. If they had different atomic numbers, they would not be the same atom and would be different elements. Different isotopes have different mass numbers.
Uranium is a chemical element. Uranium has three natural isotopes (234, 235, 238) and 26 artificial isotopes.
Both polonium and uranium have different isotopes. You can't simply compare one element to another; you have to compare individual isotopes. Check the Wikipedia articles (or other sources) on Uranium and Polonium, to get a list of common isotopes; the isotopes that has the shortest half-life will decay fastest, and can thus be said to be "more radioactive".
All the isotopes of uranium has 92 protons and 92 electrons, only the number of neutrons is different.
Uranium-235 and uranium-238 are two different natural, radioactive isotopes of uranium.
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
Uranium is a radio active metal element. Atomic mass of it is 239.
Uranium-235 and uranium-238 are different isotopes of the element uranium. They have different mass numbers due to different numbers of neutrons.
The natural isotopes of uranium are U-234, U-235, U-238.Uranium has also 26 artificial isotope and isomers.
- All the isotopes of uranium are unstable - All the isotopes of uranium are radioactive - All the isotopes of uranium have 92 protons and 92 electrons
No, only the number of neutrons is different.
Isotopes are atoms of the same element but with a different number of neutrons.Example for the isotope 228 of uranium:- uranium-228- U-228-- 22892U
That depends on the isotope! Just like (basically) any other element, Uranium has different isotopes. Check the Wikipedia article on "Isotopes of uranium" for more details.
- the atomic number of carbon is 6 and the atomic number of uranium is 92- carbon has 2 stable isotopes; uranium has only unstable, radioactive isotopes- uranium has fissile or fertile isotopes; carbon hasn't- the electron configuration is very different- the atomic radii are very different- the atomic weights are very differentetc.
Uranium has 3 natural isotopes (234, 235, 238) and 26 artificial isotopes.All the isotopes of uranium are radioactive.
The most important isotopes of uranium are 235U and 238U (natural isotopes).
