ProfessorWhen electricity flows through noble gases, they become ionized, meaning their atoms lose or gain electrons to form charged particles called ions. This process can result in the gases emitting light, which is the basis for neon lights and other types of gas discharge lamps.
My chem is a bit rusty when it comes to the noble gases, but I believe they would be very un-responsive as they all have full outer elecron shells. This makes them 'lazy', ie: they are balanced on the outer and tend not to be 'compelled' to bond and fill their outer shell as it is full. Noble gases are stable, very unlikely to react.
edit: a notable point is that this lack of 'reacting' to electricity is actually how they were discovered in very early experiments.

What happens during a volcano eruption?
During a volcano eruption, hot molten rock (magma), ash, and gases are expelled from the volcano. This can lead to lava flows, ashfall, pyroclastic flows, and volcanic gases being released into the atmosphere. Eruptions can also trigger other hazards like lahars (mudflows), landslides, and tsunamis.
A volcano erupt when molden rock flows through a central opening which is called?
A volcano erupts when molten rock, known as magma, flows through a central opening in the Earth's crust called a vent. This release of magma, gases, and ash can result in a volcanic eruption.
Which gas filled in CFL?
Compact fluorescent lamps (CFLs) are filled with mercury vapor and inert gases like argon and krypton. When electricity flows through the gas, it produces ultraviolet light that excites the phosphor coating inside the bulb, creating visible light.
Air is primarily composed of nitrogen and oxygen gases which state of these gases can conduct electricity?
These gases are not conductive.
What is hot glowing rock that flows on cushion of hot gases?
That is molten lava flowing on a cushion of hot gases, typically seen in volcanic eruptions.
What happens when electricity passes through you?
Set up properly, you will create electrolysis. Oxygen and hydrogen will disassociate form each other and be turned into gases.
What happens when electricity pass through water?
Set up properly, you will create electrolysis. Oxygen and hydrogen will disassociate form each other and be turned into gases.
Is a plasma ball potential energy?
A plasma ball does not store potential energy itself, but the electricity that powers it does have potential energy. This potential energy is converted to light and heat energy when the electricity flows through the gases in the plasma ball, creating the unique visual effects.
What glows red with electricity?
A glass tube filled with neon gas with an electrode at each end will glow red-orange when electricity flows through it.
Can eletricity travel through solids and liquids and gases?
Yes, electricity can travel through solids and liquids as they contain charged particles that can conduct electricity. However, gases are poor conductors of electricity as they have fewer free-moving charged particles than solids and liquids.
What will happen to the molecules of compound eg water when electricity pass through it?
When electricity passes through water, the hydrogen and oxygen separate and bubble off as gases.
What are two ways that heat flows within the earth?
Heat flows within the Earth through conduction, which is the transfer of heat through a material without any movement of the material itself, and convection, which involves the movement of heat through the circulation of fluids or gases.
What is the state of matter flows freely?
Gases.
What flows are violent explosions of ash cinders and bombs and gases from a volcano?
Pyroclastic flows.
What happens to the air in the mouth?
Air in the mouth is either exhaled out when we speak or breathe, or it may be swallowed down into the digestive system. It flows through the respiratory system to exchange gases in the lungs, providing oxygen to the body and removing carbon dioxide.
What is an opening in Earth's crust through which lava flows?
An opening in Earth's crust through which lava flows is called a volcano. When pressure from molten rock beneath the surface builds up, it can erupt through the volcano, releasing lava, ash, and gases into the surrounding area.
What does a light bulb consist of?
A light bulb consists of a glass bulb, a filament (or LED in the case of LED bulbs), metal contacts, and inert gases like argon or nitrogen sealed inside. When electricity flows through the filament, it heats up and produces light, illuminating the bulb.
