| Isotope | Atomic Mass (uncertainty) [u] | Abundance (uncertainty) |
|---|---|---|
| 23Na | 22.989 769 28(2) | 1 |
What are the 13 isotopes of sodium?
Isotopes of Sodium: Sodium-24, Sodium-22, Sodium-23, Sodium-22m, Sodium-24m, Sodium-18, Sodium-19, Sodium-20, Sodium-21, Sodium-25, Sodium.
Is sodium-23 naturally occurring?
MRI using 23Na The main prerequisites are a nonzero nuclear spin and a sufficient concentration to be detectable by means of nuclear magnetic resonance (NMR). The only naturally occurring isotope of sodium (23Na) fulfills all of these requirements, but lacks the sensitivity of protons.
What is the protons of sodium-23?
11
sodium-23/Protons
What is the use of sodium-23?
Functional magnetic resonance imaging Because sodium-23 (23Na) has an odd number of protons and/or neutrons it possesses a net nuclear spin and can exhibit the MR phenomenon. Na MRI has been shown to be useful in musculoskeletal imaging owing to the natural abundance of sodium in articular cartilage.
What is sodium-23 used for?
It has been shown that 23Na double-quantum-filtered NMR spectroscopy can be used to detect anisotropic motion of bound sodium ions in biological systems. The technique is based on the formation of the second-rank tensor when the quadrupolar interaction is not averaged to zero.
How many neutrons does sodium 20 have?
| Sodium-12 | Sodium-20 | |
|---|---|---|
| # of protons | 11 | 11 |
| # of neutrons | 1 | 9 |
| # of electrons | 11 | 11 |
What is the half-life of sodium-23?

| Mass Number | Half-life | Decay Mode |
|---|---|---|
| 23 | STABLE | – |
| 24 | 14.997 hours | Beta-minus Decay |
| 24m | 20.18 milliseconds | Isomeric Transition |

How many protons neutrons and electrons does an atom of sodium 23 have?
An atomic number of 11 means this atom will have 11 protons. A mass number of 23 means 23 – 11 this atom will have 12 neutrons. Since this atom is neutral the positive protons must be equal to the negative electrons. This atom will have 11 electrons.
