No, Uranium-235 and uranium-238 are radioactive, natural isotopes (not molecules, but atoms) of the one and the same element: uranium.
Both with 92 protons and 235-92 = 143 neutrons in U-235 but 146 neutrons in U-238.

What is the meaninq of two isotopes stable and unstable isotopes?
Isotopes are atoms of the same element with different numbers of neutrons. Stable isotopes have a balanced number of protons and neutrons, meaning their nuclei do not decay over time. Unstable isotopes, also known as radioactive isotopes, have an imbalance of protons and neutrons, causing their nuclei to decay and emit radiation over time.
What is isotope and radio isotope?
Isotopes are atoms of a particular element with different numbers of neutrons. A radio isotope is an isotope that is radioactive because the nucleus is unstable.
What does isotopes?
All atoms of an element contain the same number of electrons and protons but they can have different numbers of neutrons. Atoms with different numbers of neutrons are isotopes.
Different isotopes of an element contain different numbers of which particles?
The number of neutrons differ for each isotope of a chemical element.
Do atoms have different numbers of protons and neutrons?
yes
Will an atom with more neutrons react identically to an atom of the same element with fewer neutrons?
Not always. Some atoms of the same element with different numbers of neutrons are radioactive, whereas the other atoms are not.
Isotopes of an element have a different number of?
neutrons

Are protons neutrons and electrons atoms?
No they are not in the same way that arms and legs are not people.Protons, neutrons and electrons can come together in some specific numbers form atoms (or molecules). You can also have electrons by themselves. Normally you will not find isolated neutrons and protons. Alpha particles are 2 protons+2 neutrons which are found in radioactive decay.
what is isotop?
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element. Example : carbon12 Isotopes are different versions of an element with varying numbers of neutrons in their nucleus. They have the same number of protons but different numbers of neutrons. These variations in neutrons give each isotope a different atomic mass. Isotopes can be stable or radioactive, and they play a crucial role in various scientific fields like medicine, archaeology, and environmental studies.
What is isotope and radio isotope?
Isotopes are atoms of a particular element with different numbers of neutrons. A radio isotope is an isotope that is radioactive because the nucleus is unstable.
How has the amount of earths radioactive isotope changed over time?
Many elements have naturally occurring isotopes, varieties of the element that have different numbers of neutrons in the nucleus.
What is the difference between ions and isotopes?
An isotope is two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei. An ion is atom or molecule with a net electric charge due to the loss or gain of one or more electrons. Usually, isotopes are radioactive and only there neutrons differ. Ions are molecules that gain or lose electrons to fill their outer energy level.

What are the changes in neutrons?
Atoms with different numbers of neutrons are called isotopes.
Isotopes exist because atoms of the same element can have a different numbers of what?
Isotopes are different atoms of the same element with the same number of protons (proton number) but different in number of neutrons. Given that nucleon number is equal to the sum of proton and neutrons in the nucleus of an atom, isotopes have different nucleon number due to difference in number of neutrons.
