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.
What else can I help you with?
Is Sodium a period 3 element that is highly reactive?
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.
Which element is the least reactive in period 4?
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.
What is he element is found in the same period as sulfur and argon and that is more reactive than sulfur and argon?
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.
Is potassium more reactive than argon?
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.
What element produces a bright yellow glow in street lights?
Sodium is the element that produces a bright yellow glow in street lights. This is primarily due to the emission of light in the sodium vapor inside the lamp.
Is sodium is a noble gas?
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.
What element is a reactive gas?
Noble gases include Neon, Argon, Krypton, Xenon, Radon, Helium, and ununoctium.
What is more reactive with nitrogen krypton or argon?
Neither. Both argon and krypton does not react with nitrogen.
What element is a non reactive gas?
Noble gases include Neon, Argon, Krypton, Xenon, Radon, Helium, and ununoctium.
Is Argon or sodium more reactive?
sodium
What element is a non reactive noble gas?
Noble gases include Neon, Argon, Krypton, Xenon, Radon, Helium, and ununoctium.
Which element has same electron as argon?
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.
What element rhymes with polygon?
Krypton, Argon
Which element of these 4 has the most protons argon nitrogen chlorin krypton?
Krypton has the most protons among argon, nitrogen, chlorine, and krypton. It has 36 protons.
What are non reactive gases?
helium neon argon krypton xenon radon
Is Sodium a period 3 element that is highly reactive?
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.
What type of element are Argon krypton and xenon are?
They are noble gases.
