neon
Neon gas gives off an orange - red color when electricity is passed through it.
A glass tube filled with neon gas with an electrode at each end will glow red-orange when electricity flows through it.
When electricity is passed through neon gas at low pressure, it emits a bright orange-red glow. This phenomenon is used in neon lights and signs.
Sulfur dioxide gas passed through an acidic dichromate solution turns the solution from orange to green.
When electricity is passed through acidified water, bubbles are formed because the electricity causes the water molecules to split into hydrogen gas and oxygen gas through electrolysis. The hydrogen gas is formed at the cathode and the oxygen gas is formed at the anode, creating bubbles as they escape from the solution.
Neon gas gives off an orange - red color when electricity is passed through it.
Here is a website that will help you out with Helium as well as other gasses that emit colours when in a glass tube with electricity running through at the related link.

An electric discharge through neon gas gives a reddish-orange glow which is most commonly used in advertising signs and lamps.
When electricity is passed through neon gas at low pressure, it emits a bright orange-red glow. This phenomenon is used in neon lights and signs.
Phosphorus is a non-metal that glows when electricity is passed through it. It emits a light known as phosphorescence.
Electricity is passed through a wire from battery to bulb
Sulfur dioxide gas passed through an acidic dichromate solution turns the solution from orange to green.
When electricity is passed through a gas, it causes the gas atoms or molecules to become excited and emit light at specific wavelengths. Each gas has a unique set of energy levels, so when electricity is passed through it, the emitted light will reveal the characteristic color associated with that specific gas.
Neon is a colourless , odourless gas. It glows only when an electrical discharge is passed through it; Neon lights.
Electricity is produced in power station and then passed through to a generator. The generator passes the electricity through lines and then to another generator. it is again passed through lines and then to a primary customer which may be an industry or an electricity company. It is then passed on to a secondary customer through power lines through to your house.
Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric current is passed through them.
