-Gases have no definite shape or volume. -Gases are compressible and expand to fill their container. -Gases are highly mobile and diffuse rapidly.
The discovery of the noble gases (inert gases) in 1894 by Sir William Ramsay and Lord Rayleigh allowed for the revision of the earlier periodic law. These new elements did not fit into the previously established periodic table but found their place as a new group on the far right side.
The discovery element that led to the addition of Group 0 (noble gases) was the realization that certain elements, such as helium, neon, and argon, were chemically inert and did not readily form compounds with other elements. This unique behavior distinguished them from previously known elements and necessitated the creation of a new group to accommodate them.
Helium, argon, krypton, xenon, and radon are noble gases like neon. They are colorless, odorless, and have low reactivity. Neon is most similar to argon in terms of properties and behavior.
William Ramsay discovered the noble gases by isolating and characterizing them in collaboration with Lord Rayleigh. They identified argon in 1894, followed by helium, neon, krypton, and xenon. Their work led to the discovery of a new group of inert gases that did not chemically react with other elements.
Robert Boyle
Noble gases explain the stable behavior of any element and hence enhances the concept of atom's structure.
Gases are substances with very weak bonds between molecules.
Added a new column.
They are inert gases.
* Give their names. * Tell what they do. * Explain how this affects the planet. * Explain where they come from naturally. * Explain where the extra gases have been coming from in the past 250 years. * Explain how this is dangerous. * Explain what will happen if we don't stop this increase. * Explain what governments and industry can do to stop it. * Explain the changes that families and individuals can make to help the situation.
Gases are not restricted by gravity, so the molecules fly around, rather than stick together.
The discovery of the noble gases led to the addition of the group 0, which is also designated as group 18/VIIIA.
the gas
They sink below the air.
5 properties of gases are: Gases have the lowest density of all the normal 3 states of matter. Gases have a random arrangement. Gases are the only normal state of matter to be compressed. Gases have the weakest atomic forces between particles. Gases, if stripped of their electrons, form plasmas.
