Subtract the atom number from the mass number to get the neutron. Mass number is the sum of neutrons and electrons. Atom number is the number of electrons. the number of electrons is equivalent to the number of protons.

Does the number of neutrons tell what element it is?
no
What does the mass number tell about an isotope?
The number of protons and neutrons in the element
What does the protons and neutrons tell you about the oxygen atom?
protons will tell the atomic number (8) the sum of protons and neutrons will give the mass number of the element
How many neutrons are in an atom with the mass number being 186?
The atomic number (number of protons) of the element is needed to tell the number of neutrons. Mass number = atomic number + number of neutrons.
How is the number of neutrons in an atom worked out?
they work because in every atom there is a neutron, electron and proton. the electron will tell you what the atomic number is and the neutrons and protons will tell you what element it is.
How can you tell how many nucleons are in an element?
total number of protons and neutrons in the nucleus.
What does the atomic number tell you about the parts of the element?
The atomic number of an element tells you the number of protons and neutrons that element has. Since an atom has a neutral charge, the number of electrons must equal the number of protons, so you can also tell the number of electrons that element has.
What does an element's mass number tell us?
The mass number tells you the number of Protons and Neutrons in an atomic nucleus.
What does the atomic number of an element tell you about its atom?
It would tell you how many neutrons make up the Nucleus of the atom.
How many neutrons does the element U have?
The amount of neutrons can always be found by taking the atomic number from the mass number. Uranium has 146 neutrons. It depends on the isotope. See the link below for a list of uranium isotopes and how many neutrons are in each. You cannot tell how many neutrons it has with the given information. The most abundant isotope happens to be 238U, which has 146 neutrons.
What are the element number of neutrons?
Number of Neutrons = Mass number - Number of Protons
Isotopes of an element have a different number of?
neutrons
