The number of neutrons in an element is determined by subtracting the atomic number from the atomic mass number rounded to the nearest whole number. On the other hand, very few atoms are abnormal and have a different amount of neutrons than other atoms of the same element. These are called isotopes and are indicated by a number following the element symbol (eg. C-14). This is a radioactive isotope of carbon that has six protons based on the atomic number and two more neutrons than normal--8. (8+6=14). Finally, the reason that the atomic mass units end in decimals is that this is just an average weight. The isotopes can either bring this number up or down. atomic number [ 6 ] symbol [ C ] mass (atomic mass units (amu)) [ 12.01 ]
Yes, isotopes of an element are the same element but with different numbers of neutrons in the nucleus and thus different atomic masses.
Phosphorus and sulfur both have 16 neutrons.
You are probably referring to neutrons which are often found within the nucleus of an atom in numbers different from the protons. An atom of the element carbon, for instance, normally consists of 12 protons, 12 electrons and 12 neutrons. However, an isotope of carbon known as C13 consists of 12 protons, 12 electrons and 13 neutrons.
The neutron; the proton determines the element of the atom, but different atoms of the same element can have different atomic masses, due to the different number of neutrons of the atoms. Atoms of same element having same number of protons but different number of neutrons are called Isotopes. Thus, neutron determines the isotope of an atom.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
total number of protons and neutrons in the nucleus.
no
There are 118 neutrons in the element gold.
there are 61 neutrons in a the element silver
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.
The atomic number (number of protons) of the element is needed to tell the number of neutrons. Mass number = atomic number + number of neutrons.
Hydrogen has 0 neutrons
It would tell you how many neutrons make up the Nucleus of the atom.
protons will tell the atomic number (8) the sum of protons and neutrons will give the mass number of the element
Sulfur has 16 neutrons. To find out how many neutrons an element has you subtract the atomic number of that element by the atomic mass. omg thank you so much
about 66 or 64
Neon has 10 protons and 9 neutrons.
