The atomic number of Re is 75 The atomic mass of one of its isotopes is 186 How many neutrons are in an atom of this isotope?
The Atomic Mass minus the atomic number equals the number of neutrons. Thus in the case above the number of neutrons would calculate out to be 11. HOWEVER PLEASE NOTE Rhenium (Re) does not have an atomic mass of 86, it has two isotopes one of atomic mass 185 and another of atomic mass 187. Thus the real number of neutrons is 110 or 112.

How do you determine the isotope?
Isotopes are determined by the number of neutrons in an atom's nucleus. Each isotope of an element has the same number of protons in its nucleus but a different number of neutrons. Isotopes of an element have the same chemical properties but different atomic masses.
The metal tantalum has an atomic number of 73 an two isotopes with the atomic weight of 180 and 181. How many neutrons are there in the nucleus of tantalum's two isotopes?
If you subtract the atomic number form the atomic mass then the answer is the number of neutrons.
Which atomic property is different in each isotope of an element?
The number of neutrons in the nucleus is different in each isotope of an element. Isotopes of an element have the same number of protons (atomic number) but different numbers of neutrons, leading to variations in atomic mass.
Does lead isotopes have the same neutrons?
NO,each isotope has different number of neutrons why that? in isotopes the mass number is changed but atomic number(protons) still constant,thus the number of neutrons will be changed
How is an isotope and mass number related?
It isn't, as such. Isotopes of the same element have different numbers of neutrons, and neutrons have a mas of one atomic mass unit (amu). So isotopes have different atomic masses, but being told the number of neutrons any isotope has, will not enable you to say what element or atomic mass it had, unless you remembered the details for every single isotope. Even then different elements can have the same number of neutrons. Isotopes do get named after their atomic mass however - uranaium 235 has an atomic mass of 235, for instance.
How many neutrons do ununquadium have?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of ununquadium is114; uuq has five isotopes, each with a different number of isotopes..
How do you determine the isotope?
Isotopes are determined by the number of neutrons in an atom's nucleus. Each isotope of an element has the same number of protons in its nucleus but a different number of neutrons. Isotopes of an element have the same chemical properties but different atomic masses.
How many neutrons calcium?
The number of neutrons is the difference between the Atomic Mass of an isotope and the atomic number of the element; each isotope of calcium has a different number of neutrons. See the link below for calcium isotopes.
How many neutrons and electrons does dubnium have?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of dubnium is 105; dubnium has many isotopes and of course each idotope has a different number of neutrons - dubnium has now 13 isotopes and 1 isomer.
How many neutrons does the element fermium have?
Only isotopes Fr-221 and Fr-223 are natural.
The metal tantalum has an atomic number of 73 an two isotopes with the atomic weight of 180 and 181. How many neutrons are there in the nucleus of tantalum's two isotopes?
If you subtract the atomic number form the atomic mass then the answer is the number of neutrons.
What is the number of neutrons in the element sulfur?
The number of neutrons in an atom depends on the isotope. The most common sulfur isotope has 16. The average number of neutrons in an atom of sulfur is about 32.065.

How much neutrons are in xenon?
Each isotope of an element has a different number of neutrons. Number of neutrons = Atomic mass of the isotope - Atomic number of the element The atomic number of xenon is 54. For the list of xenon isotopes see the link below.
How many neutrons are in roentgenium?
Roentgenium-272 has 161 neutrons. Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of roentgenium is 111, but Rg has many isotopes each with a different atomic mass and number of electrons.
