What is a gaseous element called?
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
What are the gaseous elements?
What are Gaseous Substances? A look at the periodic table shows us that there are 11 elements in the table that exist in the gaseous state at room temperature. These elements are Hydrogen, Helium, Nitrogen, Oxygen, Fluorine, Chlorine, Neon, Argon, Krypton, Xenon, and Radon.
How do you describe a gaseous substance?
Gases are substances that exist in the gaseous phase. Gases do not have any defined volume. They expand to occupy the volume of the container they are placed in. Gases do not have any defined shape.
How can gases be defined?
(Entry 1 of 2) 1 : a fluid (such as air) that has neither independent shape nor volume but tends to expand indefinitely. 2a : a combustible gas or gaseous mixture for fuel or lighting especially : natural gas.
What is a gaseous compound?
A gas is one of the three classical states of matter (the others being liquid and solid). A pure gas may be made up of individual atoms (e.g. a noble gas or atomic gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).
Why noble gases are called Aerogenes?
– The noble gases are the chemical elements present in group 18 of the periodic table. They are the most stable as they have the maximum number of valence electrons present in their valence shell . So as the noble gas is present in the atmosphere so it is also known as aerogenes.
What is gaseous form?
Definition of gaseous 1 : having the form of or being gas also : of or relating to gases. 2a : lacking substance or solidity.
What is the another word for gas?

What is gaseous atom?
Hint: Basically, a gaseous atom is an atom in its gaseous state i.e. it has been excited from its original state and has been crossing all the forces of attraction to be free in the gaseous state. Whereas, ground state describes the state of an element when no external energy is provided to it.
What is the idiom for gas?

What is a gaseous element?
A gaseous element is defined as any element that is a gas at room temperature. For Example, all of the Inert Gases are gaseous elements as they are a gas at room temperature. In total, there are 11 gaseous elements on the Periodic Table.
What does the gaseo mean?
The gaseous state is one of the four fundamental states of matter (along with the solid state, the liquid state and plasma). Substances that exist in the gaseous phase are commonly referred to as gases. The most common example of a gas is air (the air we breathe is a gas).
What is an example of a gaseous substance?
Gaseous substances include many binary hydrides, such as the hydrogen halides (HX); hydrides of the chalcogens; hydrides of the group 15 elements N, P, and As; hydrides of the group 14 elements C, Si, and Ge; and diborane (B 2 H 6 ).
What is the definition of gas in chemistry?
Chemistry Glossary Definition of Gas. A gas is defined as a state of matter consisting of particles that have neither a defined volume nor defined shape. It is one of the four fundamental states of matter, along with solids, liquids, and plasma. Under ordinary conditions, the gas state is between the liquid and plasma states.
