What else can I help you with?
Does the moon have any resources?
The Moon has a gas called Helium 3, which is useful for Nuclear Fusion.
Are there any atoms that have no neutrons?
Yes, 1H (Hydrogen-1), the most common isotope of hydrogen has a single protons and no neutrons.
Are there any other isotopes of the element Helium?
He-3 and He-4 are stable, He-5 and He-6 have very very short half-lives. Hoisington, Nucleonics Fundamentals, McGraw Hill, 1959
Can all radioactive isotopes be used in radiometric dating?
No, not all radioactive isotopes be used in radiometric dating. Some have very very short half lives and would entirely disappear before any useful period of time passed.
Are there any naturally occurring isotopes of technetium?
Uranium deposits may contain infinitesimal amounts of technetium isotopes.
What is neon-20 and neon-22 called?
Neon-20 is used for the same things as any other natural isotopes of neon. E.G. it is used to make neon lights and helium-neon lasers. Neon-20 isotopic concentration may be important for some geological or volcanlogic studies.
Is there any gas that does not expand when heated?
Helium gas does not expand significantly when heated due to its low molar mass and weak intermolecular forces. This property makes helium useful in applications that require precise control of volume and pressure.
What are 3 families that contain no radioactive?
Three families of elements that contain no radioactive isotopes are the noble gases (such as helium, neon, and argon), the alkali metals (such as lithium, sodium, and potassium), and the alkaline earth metals (such as beryllium, magnesium, and calcium). These families consist of stable elements that do not have any naturally occurring radioactive isotopes.
Are there any artificial isotopes of fluorine?
Fluorine has 2 natural isotopes, 16 artificial isotopes and 1 artificial isomer.
Tin has the most stable isotopes of any element How many stable isotopes does it have?
It has 10
Does helium have any alloys?
No, helium is a noble gas and does not have any alloys or metallic properties.
Why does helium change the humans voice and not any other gas?
Helium is not the only gas that will make a voice change, but in most cases you can't inhale other gases without doing substantial harm to yourself. Hydrogen would have approximately the same effect as Helium, but it's so reactive that it would not be safe to inhale; Nitrogen and Oxygen are the gases you normally breath, so would create a normal sound. Neon is very near to those in atomic weight. Fluorine gas is nearly the same but quite deadly, as is chlorine. Only nonradioactive isotopes of the inert gases might be safe to inhale, and the heaviest of those would have an effect opposite that of the Helium.
