Krypton is a component of the Earth atmosphere.
Helium is more unreactive than krypton. Helium is a noble gas located in the first group of the periodic table, making it the least reactive element. Krypton, also a noble gas, is located in the same group but is slightly more reactive than helium.
It is Krypton!
Krypton is a gas.
Krypton (Kr) is a noble gas located in Group 18 of the periodic table. It has a total of 8 valence electrons, as elements in this group typically have a full outer electron shell. This configuration contributes to Krypton's chemical stability and low reactivity.
