Sodium.
Neon, Argon, and Krypton are all inert gases. They don't react with pretty much anything. However, if you put a piece of sodium metal in water, it practically explodes, that's how reactive it is.
Mainly because all it has in it's outermost electron shell is one electron, and so it wants to lose that one in order to be stable.
Sodium is indeed a period 3 element in the periodic table. It is classified as an alkali metal and is highly reactive due to its tendency to lose its outermost electron easily.
Noble gasses are least reactive of all the elements. So the least reactive element in the period 4 is Krypton. It is a noble gas with an atomic number of 36.
The element found in the same period as sulfur and argon, and more reactive than both, is chlorine. Chlorine is a highly reactive nonmetal that belongs to the same period (or row) as sulfur and argon on the periodic table.
Yes you are correct, potassium being an alkali metal is definitely more reactive than argon which is a noble gas (group 18 element). Potassium reacts violently with just water while argon is very inert and stable, which is why it remains in the atmosphere as a monatomic element.
Helium, Neon, Argon and if another Krypton.
No, sodium is not a noble gas. It is a reactive metal that belongs to the alkali metal group in the periodic table. Noble gases are a group of non-reactive elements that include helium, neon, argon, krypton, xenon, and radon.
Noble gases include Neon, Argon, Krypton, Xenon, Radon, Helium, and ununoctium.
Neither. Both argon and krypton does not react with nitrogen.
Noble gases include Neon, Argon, Krypton, Xenon, Radon, Helium, and ununoctium.

sodium
The element that has the same number of electrons as argon is Krypton (Kr). Both argon (Ar) and krypton (Kr) have 18 electrons in their neutral state.
Krypton, Argon
Krypton has the most protons among argon, nitrogen, chlorine, and krypton. It has 36 protons.

Na represents the chemical element sodium. Neon, helium, and argon are other elements on the periodic table. Sodium is a reactive metal commonly found in salt compounds.
