What are the three elements that exist in the gaseous state at room temperature?
The three elements that exist in the gaseous state at room temperature are helium, nitrogen, and oxygen.
Names of any two elements which are found in gaseous state?
Examples: argon, nitrogen.
Why does ionization take place in gaseous atoms?
Because in gaseous state all the atoms are comparable. In natural state some atoms (Elements) exist in solid state some in liquid and some in gaseous state.
Which are the elements existing in gaseous state?
Nitrogen, Oxygen, Fluorine, Chlorine, Helium, Neon, Argon, Krypton, Xenon, Radon
What is Neptune's state of matter?
Neptune is a gas giant in our solar system, primarily composed of hydrogen and helium with traces of other compounds like methane and water. Therefore, it exists in a gaseous state.
Why elements in gaseous state emit radiation?
They do not! Most gases do not emit radiation.
What are the three elements that exist in the gaseous state at room temperature?
The three elements that exist in the gaseous state at room temperature are helium, nitrogen, and oxygen.
What is the process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state is called?
The process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state is called evaporation. This occurs when the kinetic energy of the molecules overcomes the intermolecular forces holding them in the liquid state.

Examples: argon, nitrogen.
What is the process by which molecules at the surface of a liquid absorb enough energy to change to a gaseous state?
The process is called evaporation. Molecules at the surface of a liquid gain energy from the surroundings, typically heat, causing them to overcome the intermolecular forces holding them together. Once they have enough energy, these molecules transition to the gaseous state and escape from the liquid surface.
Is it true a compound is always in the same physical state as its elements?
Not always. A compound's physical state can be different from the physical states of its individual elements. For example, table salt (sodium chloride) is a solid compound, despite its elements sodium and chlorine being in gaseous and liquid states, respectively, at room temperature.
What is evaporation do when its outside?
Evaporation- The process which molecules at the surface of a liquid, such as water, absorb enough energy to change to a gaseous state, such as water vapor.
What state are all the other elements at room temp?
Most are solid, some are gaseous, and one or two are liquid.
How does the physical state of elements change as atomic number increases?
metal -->nonmetal --> gaseous (metal --> nonmetal --> metalloid)
Why does ionization take place in gaseous atoms?
Because in gaseous state all the atoms are comparable. In natural state some atoms (Elements) exist in solid state some in liquid and some in gaseous state.
Infer what state hydrogen and helium would be in at room temperature?
Both the elements exist in gaseous states at room temperatures.
Which are the elements existing in gaseous state?
Nitrogen, Oxygen, Fluorine, Chlorine, Helium, Neon, Argon, Krypton, Xenon, Radon
