What else can I help you with?
What would you expect to find as individual atoms in earths atmosphere?
Argon, You would only expect to find the noble gases He, Ne, Ar, Kr, Xe, Rn as monatomic gases. All other gases have at least two atoms e.g O2, N2 some habve more e.g. CO2
Why noble gases present in large amount in air?
Noble gases are present in small amounts in air, with only about 1% being argon. This is because noble gases are chemically inert and do not easily react with other elements to form compounds. As a result, they remain as single atoms in the atmosphere and are not consumed in chemical reactions.
How do the physical and chemical properties of the halogens compare with those of the noble glasses?
Halogens are extremely reactive, noble gases are very unreactive. All noble gases are gases; only F and Cl are gases.
Which noble gas only has one atom?
All noble gases have only one type of atom
What are the families that contain a full octet of valence electrons?
This is the family of noble gases (group 18).
Why cant noble gases mix with other elements?
!. Noble gases can be mixed with other gases. 2. Noble gases are unreactive (only a limited number of compounds are known today) because the valence electron shell is completely filled.
Which noble gas doesn't have 8 outer electrons?
Helium has only 2 valence electrons. The rest noble gases have eight.
What gas is not found in the atmosphere?
While the Earth's atmosphere comprises gases like nitrogen, oxygen, and carbon dioxide, some gases are not typically found in significant amounts. For example, noble gases like radon are present only in trace amounts and are not considered part of the primary atmospheric composition. Additionally, gases such as hydrogen sulfide or methane may be found in localized areas but are not prevalent in the overall atmosphere.
What is the outer shell of the noble gases called?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration.
Where does krypton occur naturally?
Krypton is a noble gas and occurs naturally in trace amounts in the Earth's atmosphere. It is a colorless, odorless gas and is one of the rarest gases in the atmosphere, making up only about 1 ppm (parts per million) by volume.
How do the physical and chemical propertys of the halogens compare with those of the inert gases?
Halogens can be gaseous, liquid or solid; noble gases are only gases.Halogens are very chemical reactive elements; only some compounds of noble gases are known.
