Sulfur has 4 naturally occuring stable isotopes: 32, 33, 34, 36.
No. Gallium is an element. The element Gallium has two naturally occuring stable isotopes (69Ga and 71Ga) and abpout 29 unstable isotopes.
Potassium has 3 naturally occuring isotopes 39K, 40K, 41K It has an atomic number, (number of protons), of 19 so it contains 20, 21 or 22 depending on the isotope.
Xenon has eight stable naturally occuring isotopes. Besides these stable forms, there are over 40 unstable isotopes that have been studied.
Salt substitute - contains potassium chloride. A slight amount of naturally occuring potassium is radioactive.
Because bananas are high in potassium, they have naturally occurring isotopes of potassium, of which potassium-40 is one.
Both the masses and the relative abundances of the individual isotopes
No. Naturally occuring indium is not radioactive. there are many isotopes of indium created artiificially, many of these are radioactive. See wikipedia "Isotopes of indium" for a list.
Potassium is an isotope. There are many isotopes of potassium, the most common naturally occurring isotope having mass number 39 (39K). The next most common natural potassium isotopes are 40K and 41K.
Radium, by a big margin. Radium has no isotopes that are not radioactive, but no naturally occurring isotopes of potassium or sodium are radioactive.
Average atomic mass.
39K (93.3%), 40K (0.0117%), and 41K (6.7%).
If there are 2 naturally occuring isotopes of Rubidium 85 Rb Mass 84.91u Mass 85.47u 87 Rb Mass 86.82u, then is 15 the percent abundance of each of the isotope.
The weighted average of all of the natural occuring isotopes for a particular element is called its Atomic Weight (or Relative Atomic Mass)
Radon is the heaviest naturally occuring noble gas but it is unstable. The stable and heaviest naturally occuring noble gas is Xenon.
The nomenclature "potassium-19" is not commonly used because it is redundant. The 19 in potassium-19 would indicate the number of protons in potassium. All isotopes of potassium have 19 protons. Therefore 19 is known as the atomic number of potassium. Potassium-41 is one of the three naturally occurring isotopes of potassium. It has 19 protons and 22 neutrons, giving it an atomic mass number of 41.
Potassium occurs naturally on earth in three isotopes with mass numbers 39, 40, and 41. Of these, the isotope K-40 is known to be radioactive, but has a very long half life. There are many other radioactive isotopes of potassium.
No it is naturally occuring
an example is oxygen
2 electrons. He-4 and He-3 are the two most occuring isotopes.
copper is a naturally occuring element
