Can atoms of an element have different numbers of neutrons?
Yes, such atoms are isotopes of that element. Elements have a unique number of protons, but may occur in several isotopes having different numbers of neutrons. Hydrogen (atomic number 1) always has 1 proton. It usually has no neutrons and an atomic weight near 1, but also occurs with 1 neutron and an atomic weight near 2 called deuterium, as well as occurring with 2 neutrons and an atomic weight near 3 called tritium. Some periodic tables list the most common isotopes and their relative abundance. The atomic weight listed for an element is usually the weighted average of its isotopes rather than the weight of any single isotope.
How much is 1 molecule of uranium atoms?
Each isotope of an element has a different number of neutrons. Number of neutrons = Atomic mass of an isotope - atomic number of the element For uranium the atomic number is 92; for the isotopes see the list of isotopes with their atomic mass.
What are the radioactive isotopes?
radioactive isotopes are isotopes with irregular nuclear composition, it emits energy due to decay of atomic nucleus.
Mass number Why is it not the number on the periodic table?
Elements have different isotopes and each isotope will have different atomic mass. As such it is not possible to list the mass number of all the isotopes on the periodic table. However, the atomic mass is generally given on the periodic table which is generally calculated taking into account all the isotopes and its percentage.
How many neutrons does barium have?

List the subatomic particles and isotope symbol for bromine ASAP?
All atoms of chemical elements contain protons, neutrons (excepting the isotope H-1)and electrons. The natural isotopes of bromine are 79Br and 81Br. For the list of all isotopes see the link below.
What is the slow breakdown of radioactive substances into more stable elements?
Radioactive elements break down in to stable isotopes through nuclear decay. The list of isotopes from a nuclear isotope to a stable isotope is called its decay chain.
How many nutrons does zirconium have?
The number of neutrons for any given element varies, depending on the isotopes. Search the Wikipedia, or Google, for "Isotopes of Zirconium" for the isotopes of this particular element. The list of isotopes will give you the atomic mass (protons + neutrons) for the different isotopes; subtract the atomic number (which is the number of protons) to get the number of neutrons for each isotope.

By using the periodic table how did you determine how many neutrons are the most common isotope of an element?
Usually the periodic table would not be a good source to determine the number of neutrons; the periodic table focuses on the atomic number, which is the number of protons. An element with a given number of protons can have multiple isotopes, which are elements with the same number of protons but a different number of neutrons; in some cases there are a rather large variety of isotopes. Having said that, some periodic tables do represent the commonest isotope or commonest naturally occurring one but are still unlikely to list all possible isotopes.
