Which atmospheric layer contains the fewest gases?
The exosphere is the atmospheric layer that contains the fewest gases. It is the outermost layer of Earth's atmosphere and consists of very low densities of hydrogen and helium, along with traces of other gases.
What is radioactive fossil?
A radioactive rock is one which contains traces of radioactive isotopes. These isotopes release radiation in its various forms. Any rock can be radioactive, but in particular igneous rocks tend to have radioactive properties. This is because they may have radon gas trapped in their crystals, which, under pressure, is released (this is why radon gas is used as an indicator of an upcoming earthquake). Radon gas is radioactive, and this causes the rock to be radioactive also.
Is strontium radioactive?
There are different isotopes of strontium. While some isotopes of strontium are stable and non-radioactive (e.g., strontium-88), other isotopes are radioactive (e.g., strontium-90). Strontium-90 is considered a hazardous radioactive isotope because it can be absorbed by the body and increase the risk of cancer.
What is the element for Uranus?
The planet Uranus' atmosphere contains primarily two gaseous elements. These two elements are Hydrogen (H) and Helium (He). It also contains methane (a combination of two elements - Hydrogen and Carbon - CH4). This gives Uranus it's aquamarine colour.
Are emeralds radioactive?
Emeralds themselves are not radioactive. However, some emeralds may contain traces of radioactive elements like uranium, thorium, or radium which can emit low levels of radiation, but it is typically not considered harmful to human health.
What are the periodic elements in a balloon?
A balloon typically contains the element helium, which is a noble gas. It can also contain traces of other elements such as oxygen or nitrogen from the surrounding air or manufacturing process.
What is the most common place to find helium?
Helium is a gas. It is found in traces in the Earth's atmosphere.
Which atmospheric layer contains the fewest gases?
The exosphere is the atmospheric layer that contains the fewest gases. It is the outermost layer of Earth's atmosphere and consists of very low densities of hydrogen and helium, along with traces of other gases.
What is the athmosphere on Neptune?
The atmosphere on Neptune contains helium and hydrogen with some traces of water, methane and ammonia. The atmosphere is similar to the large planets of the Solar System, but has a larger proportion of ice.
All living things on earth are radioactive true or false?
False. Not all living things on Earth are radioactive. Radioactivity is a natural process that can be found in some elements and materials, but it does not apply to all living organisms.
Create a list of element names for the 10 non radioactive gaseous elements?
Hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, xenon, and krypton are all gasses are usually found in nonradioactive isotopes. Hydrogen, chlorine, argon, and krypton have at least traces of naturally occurring radioactive isotopes, however.

Is there helium in Mars?
The tables I found list no helium, as measured by the Venera probes. If its there, it is only in minute traces. The atmosphere is extremely hot and dense, and a gas as light as helium would escape into space very quickly.
Is strontium radioactive?
There are different isotopes of strontium. While some isotopes of strontium are stable and non-radioactive (e.g., strontium-88), other isotopes are radioactive (e.g., strontium-90). Strontium-90 is considered a hazardous radioactive isotope because it can be absorbed by the body and increase the risk of cancer.
What is Saturn's material composition?
About 75% hydrogen and 25% helium, with some traces of heavier elements.
What is Saturn's composition materials?
About 75% hydrogen and 25% helium, with some traces of heavier elements.
Should helium be classified as a mixture?
Helium is one of the elements of the periodic table. Helium in the shape where people can get in contact with it may have traces of other elements in it depending on the level of purity, but it's still mainly just helium and almost nothing else.
