1. Sodium has 20 isotopes and 2 isomers.
2. Only the isotope 23Na is stable.
3. The stable isotope 23Na and the radioactive isotopes 22Na and 24Na (these isotopes exist in traces) are natural isotopes.
There are about 339 naturally occurring isotopes on Earth. 288 of these are primordial. An isotope is a variant of a particular chemical element that differ in the number of neutrons they have.
There are 18 isotopes of sodium.
Sodium has 18 isotopes but the only stable isotope of sodium is 23Na.
Every element has 3 isotopes.
one isotope

Sodium does not have naturally occurring radioactive isotopes - as it has only 1 naturally occurring isotope, which has 11 protons and 12 neutrons, and is not radioactive. However, the 18 other known types of sodium isotopes are all radioactive, and sodium-22 (the most stable radioactive sodium isotope) has a half life of 2.6 years.
Sodium-23 and Sodium-22 are two isotopes of sodium. Na-23 is the only stable isotope of Sodium. Na-22 is one of the two isomers (the other of which is Na-24).
Cheryl finds the average mass of sodium isotopes found in nature.
The number of neutrons is different.
Because atoms can be isotopes or ions, protons are the only stable identifier for an element (Sodium can have more or less than normal number of electrons or neutrons and still be sodium). Sodium has 11 protons.
Sodium has no radioactive isotopes.
Sodium is considered a monoisotopic chemical element - sodium-23; the isotopes sodium-22 and sodium-24 exist only in ultrtraces.
An isotonic solution of sodium chloride has a concentration of 9 g/L.
Sodium has two natural isotopes: Na-23 (stable) and Na-22 (radioactive, but only in traces).
Sodium does not have naturally occurring radioactive isotopes - as it has only 1 naturally occurring isotope, which has 11 protons and 12 neutrons, and is not radioactive. However, the 18 other known types of sodium isotopes are all radioactive, and sodium-22 (the most stable radioactive sodium isotope) has a half life of 2.6 years.
30 or 32 neutrons, because chlorine has two isotopes.
Sodium-23 and Sodium-22 are two isotopes of sodium. Na-23 is the only stable isotope of Sodium. Na-22 is one of the two isomers (the other of which is Na-24).
Sodium is not mono isotopic. It has two isotopes. Namely they are sodium-23 and sodium-24.
Radium, by a big margin. Radium has no isotopes that are not radioactive, but no naturally occurring isotopes of potassium or sodium are radioactive.
They have different number of neutrons
Cheryl finds the average mass of sodium isotopes found in nature.
Sodium and chlorine are elements. If you mean one sodium atom and one chlorine atom yes they would be both isotopes but of different elemnts. If they were randomly sampled from nature the sodium atom would almost certainly be sodium-23 (there is only a trace of sodium-22 found in nature) and the chlorine atom would most likely be chlorine-35 as this isotope is about 75% of chlorine)
