It is a colorless, odorless, tasteless, nontoxic, and nearly inert gas that heads the noble gas series in the Periodic Table

What is the main characteristic of a sequence star?
The defining characteristic of a main sequence star burns hydrogen to helium in its core.
How can you test for helium?
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.
What is the general characteristics of helium?
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.
What color does helium burn in a flame test?
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.
What is an important characteristic of helium?
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.
What kind of gas is in Jupiter's atmosphere?
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.
What the gender of helium?
Helium does not have a gender, I don't know what you think either of those mean but helium is that stuff you put in a balloon and when you suck it up it makes your voice really high, and gender means what sex a person or animal is (male or female)
What substance physical properties depend on the composition?
A characteristic property is a chemical or physical property that helps identify and classify substances. The characteristic properties of a substance are always the same whether the sample you are observing is large or small.
Why is helium in the noble gas column of the periodic table?
Helium has two electrons which means the "valence" orbital is full, this also means that helium is not highly reactive. All of the noble gases also have filled "valence" orbitals so helium acts more like a noble gas and is placed in that column.
What characteristic do all of the outer planets share?
All of the outer planets are large in size, low in density, and have very thick atmospheres made primarily of hydrogen and helium.
What does Jupiter and Saturn and neptune and uranus have in coment?
They have rings, but the main characteristic is that they are all gas giants, massive planets with extremly thick atmospheres composed mostly of hydrogen and helium.
Is helium a physical property or chemical property?
Helium is an element that has physical properties. So far it has eluded efforts to make it react with anything else. It could thus be argued it does not have chemical properties other than it is very inert.
