The have completely filled valence orbitals, generally chemically inert and hence considered to be noble.
Krypton has the most protons among argon, nitrogen, chlorine, and krypton. It has 36 protons.
krypton
No, argon does not form an ion isoelectronic with krypton. Argon has 18 electrons, while krypton has 36 electrons. To be isoelectronic, the two species should have the same number of electrons.
Argon is a noble gas and is typically unreactive, so it does not form many compounds under normal conditions. However, argon can form stable compounds with fluorine, such as argon fluorohydride (HArF), under extreme conditions. These compounds are usually only observed in laboratory settings or under high pressure conditions.
The balloon with krypton gas has a higher density than the balloon with argon gas.
Neither. Both argon and krypton does not react with nitrogen.
they do not for compounds except for xenon, krypton and argon. These compounds are all very unstable. The first compounds of xenon and krypton were found 50 years ago, and compounds of argon only in the last 15 years.
The density of krypton and argon are 3.749 g/L and 1.784 g/L respectively at 0oC. So krypton is heavier than argon.
Krypton has the most protons among argon, nitrogen, chlorine, and krypton. It has 36 protons.
Helium, neon, argon, krypton, xenon, and radon are inert gases that can form compounds, primarily with highly electronegative elements such as fluorine and oxygen.
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.
krypton
No, argon does not form an ion isoelectronic with krypton. Argon has 18 electrons, while krypton has 36 electrons. To be isoelectronic, the two species should have the same number of electrons.
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.
Helium, Neon, Argon and if another Krypton.
