What are noble gases best known for?
Noble gases are commonly used in lighting because of their lack of chemical reactivity. Yet even better known is helium's use in balloons because it is lighter (less dense) that the surrounding air it causes the balloon to rise. Helium is sometimes used to improve the ease of breathing of asthma sufferers. Xenon is used as an anesthetic because it can be moved quickly from the body resulting in faster recovery. Another noble gas, argon, is considered the best option for use as a dry-suit inflation gas for scuba diving. Noble gases are being used more and more like in blimps or crisp packets.
Why was prohibition known as the noble expierment?
Because it had noble intentions.
Is a helium a noble gas?
Yes helium is a noble gas because it is very stable, colorless, odorless taste less, but unlike the other noble gases, it has two electrons in its valence shell.
Is O a molecule?
O is the symbol for Oxygen, which is not a noble gas.No, Oxygen (O) is in group 6 and the noble gases (or inert gases) are in group 8.oxygen is not a noble gas because in order to become a noble gas it is necessary to have a completely filled outermost shell. as oxygen has only 6 electrons in its outermost shell it is not a noble gas because noble gases have 8 electrons which completely fill the outermost shell
What are the elements in Group 17-18 called?
The Group 18 elements are called the noble gases or sometimes inert gases. Wikipedia has information on the noble gases, and a link is provided.
Why do noble gases in balloon float in air?
Noble gases are lighter than air. Hence balloons filled with noble gases will float in air.
How do the Macy's thanksgiving parade balloons float?
Those balloons are filled with helium gas. Helium is lighter than air. Helium is a noble gas.
What quality of helium makes it useful?
Helium is lighter than air (which means it can be used to make stuff float, like balloons) and a noble gas (which means that it won't react with other elements). Both of these qualities make helium very useful.
Are all noble gases lighter than air?
No. The molar mass of dry air is 28.97 g/mol. Noble gases are monatomic, so their atomic mass represent their molar mass. From this we can tell that helium and neon are less dense (lighter) than air, while argon (atomic mass 39.9) onwards are denser than air.
What is the trend in density as you go down the group of noble gases?
The densities of the noble gases increase with increasing molecular mass. The increase in density is due to the increase in atomic mass. Helium is about one seventh the density of air and can be used in balloons and lighter-than-air craft. Xenon is about five times the density of air.
What is the trend in density in noble gases?
The densities of the noble gases increase with increasing molecular mass. The increase in density is due to the increase in atomic mass. Helium is about one seventh the density of air and can be used in balloons and lighter-than-air craft. Xenon is about five times the density of air.
What is the most popular noble gas?
Helium (in balloons, blimps and underwater diving cylinders) and Neon (in neon lights)
What is the noble gas that is heavier than F but lighter than Cl?
Neon
What properties make helium useful?
While it is not a "Noble Gas" it is much lighter than air. It is not lighter than Hydrogen, but it does not ignite as easily.

What element is colorless gas and used in balloons?
'Helium' because it is also an INERT (Noble) gas. Hydrogen could be used to make the balloon float/rise, but hydrogen is a flammable gas. On explosion you will have a flash of flame.
What is helimum?
I assume that you mean Helium ... one of the Noble Gases. It is the second lightest Element, Hydrogen is the first. Being a noble gas, it does not burn so it is used in balloons. The noble gases do not readily combine with other elements to form other compounds ... they just 'stand alone.' A balloon filled with hydrogen can and does easily explode, but one filled with helium will not
