Krypton is a Nobel gas, which means that it has a full outer valance shell of electrons. This means there are no bonds or forces between the atoms such as Van der Walls or dipoles. Rubidium however is held together by a metallic bond, which means that it's electrons are delcocalized into a sort of "sea" of electrons. This leads to attractive forces between the atoms, meaning they're held closer together and it takes more energy to separate them into a gaseous form.
What else can I help you with?
What is the melting and boiling point for krypton in fahrenheit?
Krypton melts at -251.25 °F and boils at -244.12 °F
Is the melting point of sodium higher or lower than rubidium?
Sodium has a melting point of 97.72 oC and rubidium has a melting point of 39.48 oC.
Why is neon's boiling point lower than krypton and argon?
Neon has a lower boiling point than krypton and argon because it is a smaller atom with weaker London dispersion forces between its atoms. Krypton and argon have more electrons and larger atomic sizes, leading to stronger intermolecular forces that require more energy to overcome, resulting in higher boiling points.
What is the state of krypton at 20 degrees calcious?
At 20 degrees Celsius, krypton is a colorless and odorless gas. It remains in its gaseous state at this temperature. Krypton is a noble gas with a boiling point of -153.22 degrees Celsius, so at 20 degrees Celsius, it is well above its boiling point.
Are helium and krypton similar?
Helium and krypton are both noble gases, but they differ in terms of properties. Helium is lighter and has a lower boiling and melting point compared to krypton. Krypton is also more chemically reactive than helium.

Does ethanol has the lower boiling point?
It depends what chemical or compound you are comparing the boiling point to. Ethanol has an atmospheric pressure boiling point of 78.1 °C (172.6 °F). This is slightly lower than the boiling point of water at the same pressure, much lower than the boiling point of iron, much higher than the boiling point of bromine.
Why does the boiling point of methylated spirits drop?
The boiling point of methanol is lower than the boiling point of ethanol.
