a gas that ignites a glowing splint is oxygen
The statement is true , oxygen is a gas which ignites a glowing splint.
A splint is a simple piece which is used in scientific laboratories. They are typically long, thin strips of wood of about 6 inches long and 1/4 inches wide. They are consumable and inexpensive. They are used for lighting burners , chemical identification of various gases .
For gases which are hard to distinguish , a glowing splint test is used for identification of gases. . These tests are useful for identifying whether the gas is oxidizing,flammable or chemically inert.Oxygen is one of the gases which can be identified using the splinter test as it is combustible.
For the test, the splint is lit and is allowed to burn for a fraction of seconds and then blown out as the tip is still hot it is introduced into the jar containing the oxygen gas and thus re-igniting the splinter.

To solve this we must be knowing each and every concept related to element. Therefore, "all of the noble gas elements except neon have 8 electrons in their outermost energy level" is a false element.
A chemical element represents a material that cannot be degraded chemically. Although chemical processes do not modify atoms, nuclear reactions can produce new elements.
Elements are classified according to the amount of protons they have. An element's atoms typically have the same amount of protons, but differing amounts of electrons or neutrons.
There are 118 recognized elements. Element 120.1 is being researched. When element 120 is created and validated, the periodic table must be updated to include it. A numerical subscript following an element in a chemical formula mean number of atoms. All of the noble gas elements except have 8 electrons in their outermost energy level.
Therefore, "all of the noble gas elements except neon have 8 electrons in their outermost energy level" is a false element.
