10 neutrons in Ne-20 isotope
Checking the periodic table, we can see that neon has an atomic number of 10. This means that is has 10 protons, and 10 electrons. The most stable form of neon (90,5% of all neon) has 10 neutrons, though there are two more forms of neon isotope's, one with 11 neutrons (0,3%) and one with 12 neutrons(9,3%).
A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one.
The number of neutrons in one atom can vary depending on the element. Neutrons are one of the three main subatomic particles found in an atom, along with protons and electrons. The number of neutrons in an atom is calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom.
Technetium-98 has 55 neutrons.
Titanium-47 has 25 neutrons.
There are 77 Neutrons in the nucleus of one atom of Xenon
Sodium is atomic number 11, while neon is atomic number 10. We would already expect sodium to be heavier, but the most common stable isotope of sodium has 12 neutrons, and the most common stable isotope of neon has only 10. Since the atomic weight can be approximated by the sum of neutrons and protons (and the number of protons is the atomic number), we can guess that sodium's atomic mass is 23 and neon's is 20.

One atom of (^{36}Cl) contains 20 neutrons. This can be calculated by subtracting the number of protons (which is 17 for chlorine) from the atomic mass number (36).
subtract the atomic number by the Atomic Mass, and that is the answer. if its a neutral atom, there are probably the same number neutrons as protons.
Hydrogen is the smallest atom by mass. Helium, neon, fluorine and oxygen are smaller in size. Many calculations put the helium as the smallest atom. But a few other calculations put neon as the smallest atom!
One neutron per atom of hydrogen.
