What is meant by neutral gases?
Chemically, a neutral gas is one that is stable (meaning it has 8 valence electrons in its outer level already and does not need to react to achieve these 8 electrons). These gases are also called Noble gases. Helium is considered a neutral gas because it only has one energy level and can only hold 2 electrons (Remember that the goal of elements is to achieve stability, which is why they react. An element is stable when it has 8 electrons in the outer level).
Why do gases spread and mix together faster than water?
Gases spread and mix faster than water because gases have lower viscosity and molecular interactions compared to liquids like water. This allows gas molecules to move more freely and quickly to fill the available space. Additionally, gases are compressible, meaning their volume can change easily with pressure, which also aids in their rapid mixing.
What is the meaning of KMT in chemistry?
In chemistry, KMT stands for Kinetic Molecular Theory. It is a theory that explains the behavior of gases in terms of the motion of their particles. It states that gases are made up of a large number of small particles that are in constant, random motion.
In what ways are particles in solids, liquids, and gases similar?
Particles in solids, liquids, and gases are similar in that they are all made up of atoms or molecules. They also have kinetic energy, meaning they are constantly in motion. Additionally, they can interact with each other through forces such as attraction or repulsion.
What do the names of nobles gases mean?
The Noble Gases and Their MeaningsArgon gets its name from Greek and means "inactive".Helium is from the Greek word 'helios' meaning 'sun'; the element was given this name because of its yellow appearance.Krypton comes from the word kryptos, which is Greek for "hidden one".The name neon comes from the Greek neo, meaning new. Neon was given this name when it was discovered as a new element in 1898.Although I'm not sure of this, but I think xenon means "the first"

What is the meaning of noble gases in Periodic table Group VIIIA?
Noble gases are very unreactive chemical elements.
Does this sentence clearly state its meaning The teacher returned the exams to the students without grades on them?
No. The sentence is ambigious in it's meaning. Although the reader might assume that the teacher returned exams that did not have grades marked upon them, the teacher could have been returning exams to students who were themselves not marked with grades.
Where did noble gases get their name?
These gases are called noble because they are very unreactive. Also: - helium: from the Greek word helios with the meaning sun - neon: idem with the mening of new - argon: idem, with the meaning of inactive - krypton: idem with the meaning of hidden - xenon: idem, with the meaning of strange - radon: the name is derived from radium emanation
Is Clay imperable or perable?
Clay is permeable, meaning it allows liquids or gases to pass through it. It is not impermeable, which would prevent the passage of liquids or gases.
Are helium argon and neon inactive gases?
Yes, helium, argon, and neon are considered inactive gases because they are chemically inert, meaning they do not readily react with other elements to form compounds. They are also known as noble gases.

What is the literal meaning of atmosphere?
The word "atmosphere" comes from the Greek words "atmos" meaning vapor and "sphaira" meaning sphere, referring to the layer of gases surrounding a planet. It is the enveloping layer of gases surrounding the Earth or another planet, providing the air that we breathe and playing a crucial role in regulating climate and weather.
Noble gases usually exist as what?
Noble gases usually exist as monatomic (single atom) gases because they have a stable electron configuration and are inert, meaning they do not easily react with other elements. This makes them chemically unreactive and often found in their elemental form in nature.
Can gases expand?
No, they diffuse until an equilibrium is established meaning there is an equal spread of the gasses molecules. - Tony
Why do gasses have neigthter a fixed volumn?
Because gases are compressible, meaning their volume depends on the pressure exerted on them.
Why is the layer of air that surrounds the Earth the atmosphere?
It originates from Greek atmos meaning 'vapour' and sphaira meaning 'ball or globe'. The Earth's atmosphere is a thin layer of gases that surrounds the Earth. It composed of 78% nitrogen, 21% oxygen, 0.9% argon, 0.03% carbon dioxide, and trace amounts of other gases. Because that is what the layer of gases that surround an astronomical body are called.
