Helium is a lighter-than-air gas, so it's handy for filling balloons with. Probably more "important" than that though is the fact that helium is not very reactive (it is chemically inert), and in particular it is not flammable, unlike hydrogen.
The defining characteristic of a main sequence star burns hydrogen to helium in its core.
One common way to test for helium is to use a helium leak detector, which can detect very small amounts of helium gas. Helium can also be identified using a mass spectrometer, since it has a unique mass-to-charge ratio. Additionally, helium can be detected by its characteristic orange glow when placed in an electric field.
Helium is not important for living beings.
helium is used in gas ballons .it is the lighter gas
becouse it is important
Helium is a colorless, odorless, and tasteless gas. It is the second lightest element and is non-reactive, meaning it rarely forms chemical compounds. Helium has the lowest boiling and melting points of all the elements.
Helium is an inert gas.
Helium does not burn in a flame test because it is an inert gas and does not react with the flame to produce a characteristic color.
Another important genetic characteristic of Marfan syndrome is variable expression.
Helium is the second lightest element. Helium has the lowest boiling point among all the elements. It is chemically inert.
Jupiter's atmosphere is primarily composed of hydrogen and helium, with smaller amounts of methane, ammonia, and water vapor. The high concentration of hydrogen and helium gives Jupiter its characteristic colors and properties.
An important characteristic of good money is scarcity. This means that it is not readily available which will increase its value as well.
