What is Sodiums isotope?

Isotopes. Sodium-23 is the only naturally occurring isotope of sodium. Sodium 22 and sodium 24 are two radioactive isotopes of sodium, which are used in medical applications.

What is the abundance for sodium?

Although sodium is the sixth most abundant element on earth and comprises about 2.6% of the earth’s crust, it is a very reactive element and is never found free in nature. Pure sodium was first isolated by Sir Humphry Davy in 1807 through the electrolysis of caustic soda (NaOH).

How do you calculate isotopic abundance?

As a percent, the equation would be: (x) + (100-x) = 100, where the 100 designates the total percent in nature. If you set the equation as a decimal, this means the abundance would be equal to 1. The equation would then become: x + (1 – x) = 1. Note that this equation is limited to two isotopes.

What sodium isotope is most abundant?

Na-23
Melting point: 208.04 degrees Fahrenheit (97.80 degrees Celsius) Boiling point: 1,621 F (883 C) Number of isotopes (atoms of the same element with a different number of neutrons): 21; 1 stable. Most common isotopes: Na-23 (100 percent natural abundance)

Which is the most intense isotope of sodium?

Further data for radioisotopes (radioactive isotopes) of sodium are listed (including any which occur naturally) below. Isotope abundances of sodium. In the above, the most intense ion is set to 100% since this corresponds best to the output from a mass spectrometer.

When did the Commission on isotopic abundances publish?

Since 1931, the Commission regularly publishes the critical evaluation of isotopic abundances of elements. These values form basis for the standard atomic weights of elements. Below is the current table of Isotopic Compositions of the Elements.

Where can I find the isotopic mass and abundance data?

The isotopic mass data is from G. Audi, A. H. Wapstra Nucl. Phys A . 1993, 565 , 1-65 and G. Audi, A. H. Wapstra Nucl. Phys A . 1995, 595 , 409-480. The percent natural abundance data is from the 1997 report of the IUPAC Subcommittee for Isotopic Abundance Measurements by K.J.R. Rosman, P.D.P. Taylor Pure Appl. Chem.1999, 71 , 1593-1607.

How are the 24 isotopes of sodium used in medicine?

Exposure of the human body to intense neutron flux creates 24 Na in blood plasma. Measurements of its quantity are used to determine the absorbed radiation dose of the patient. This is used to determine the level of medical treatment required. Na is created, which makes the coolant radioactive. When the 24
