How many electrons does sodium-23?
11 electrons
The mass number is given at the top left of the elements symbol, for example, sodium has a mass number of 23. We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons.
What sodium has 23 neutrons?
The atoms of both isotopes contain 11 protons, but sodium-23 has 12 neutrons whereas sodium-24 has 13. Sodium-23 is quite stable (for example, it is one of the elements in common salt – NaCl, sodium chloride).
Why is sodium-23?
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.
Is sodium-23 naturally occurring?
Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23Na. The free metal does not occur in nature, and must be prepared from compounds.
Is sodium 23 an isotope?
Sodium-23 atom is the stable isotope of sodium with relative atomic mass 22.989770, 100 atom percent natural abundance and nuclear spin 3/2.
How many electrons are in 23 11 Na+?
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.
Why is sodium special?
It’s a soft metal, reactive and with a low melting point, with a relative density of 0,97 at 20ºC (68ºF). From the commercial point of view, sodium is the most important of all the alkaline metals. Sodium reacts quickly with water, and also with snow and ice, to produce sodium hydroxide and hydrogen.
What is sodium 22 used for?
use of sodium Of the radioactive artificial isotopes, sodium-22 (2.6-year half-life, the longest half-life of a sodium isotope) is used as a radioactive tracer for natural sodium. Sodium-24 (15-hour half-life) is limited in use by its short life and is produced by irradiation in a nuclear reactor.
What is the symbol of sodium 23?

Is sodium 22 radioactive?
Of the radioactive artificial isotopes, sodium-22 (2.6-year half-life, the longest half-life of a sodium isotope) is used as a radioactive tracer for natural sodium.
Who discovered electron?
J.J. Thomson
Although J.J. Thomson is credited with the discovery of the electron on the basis of his experiments with cathode rays in 1897, various physicists, including William Crookes, Arthur Schuster, Philipp Lenard, and others, who had also conducted cathode ray experiments claimed that they deserved the credit.
What are 5 facts about sodium?
Who knew?

What is the resonance frequency of sodium 23?
Recognizing the sensitivity gain and yet unimpaired transmission field homogeneity 19 because of the comparably low 23 Na resonance frequency, which is close to 1 H MRI at 1.5 T, it is conceptually appealing to pursue 23 Na CMR at 7 T at clinically acceptable acquisition times.
