14 neutrons for Al-27 isotope.
about 66 or 64
Virtually 100% of fluorine atoms have 10 neutrons. (Wikipedia)
The element proactinium-231 has 140 neutrons (element number 91, 91 protons).
13 protons means it must be aluminum (Al). 15 neutrons means its atomic mass will be 28. This is not aluminum's most abundant isotope, but it is still aluminum.
To determine the number of neutrons, subtract the atomic number from the mass number. In this case, 208 - 83 = 125 neutrons.
There are 118 neutrons in the element gold.
there are 61 neutrons in a the element silver
Sodium-24, magnesium-25 and aluminium-26 atoms have 13 neutrons each.
Hydrogen has 0 neutrons
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

The nuclide notation for an atom with 13 protons and 5 neutrons is (^{18}_{13}Al), where the superscript is the sum of protons and neutrons (18) and the subscript is the atomic number (13) for the element aluminum (Al).
Neon has 10 protons and 9 neutrons.
