Na -23 is the most abundant isotope, because the atomic massfor Na on the periodical table of elements is 22.99 and 22.99 isclosest to 23.
Sodium-23 is the only stable isotope of sodium, so it is probably sodium-23!
The most abundant isotope of potassium is potassium-39.
Sodium 23
It also happens to be the only completely stable sodium isotope as well.
Your mom knows all the isotopes of sodium.
The isotope sodium-23 has 12 neutrons.
neon 20 =P
Hydrogen
it is the most stable isotope of sodium Na.
its 2. because its located in the 2nd period.
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.
Phosphorus-31 is the most common isotope. (Wikipedia)
The element neon has 10 protons as its atomic number is 10.
The most common isotope of Neon has 10 neutrons.
Ne-20 is the most common (91%) isotope with 10 neutrons in its nucleus. The other isotope Ne-22, with 12 neutron, is found for 9% of the naturally occurring Neon.

The most common isotope of silicon is the isotope 28Si: 92,23 %.
it is the most stable isotope of sodium Na.
its 2. because its located in the 2nd period.
Neon has 10 protons and 10 electrons per atom. 20Ne is its most common isotope. It has 20 - 10 = 10 neutrons.
The nucleus of neon contains 10 protons and 10 neutrons for the most stable isotope of neon.
Vanadium-51 is the most common isotope.
The most common plutonium isotope is plutonium 239.
The most common plutonium isotope is plutonium 239.
