Which noble gas has highest and least Polarisability respectively?

Xe due to the hightest polarisability and He has least polarisability due to the largest and smallest size of Xe and He respectively.

Which noble gas has highest positive electron gain enthalpy?

Neon has the highest positive (+ 116) electron gain enthalpy.

Why noble gases are sparingly soluble in water?

Explanation: Noble gases are non-polar substances, so the only form of intermolecular forces that they have are London dispersion forces. ... They still can dissolve, but only very little, because some water molecules will be able to form dipole-induced dipole attractions with the noble gas atom.

Does noble gas dissolve in water?

Complete answer: The noble gases are not soluble in water. The solubility in water increases as the size of noble gases increases. Noble gas is soluble in water due to the dipole-induced dipole interaction.

Why noble gases are monatomic in nature?

Noble gases are monoatomic because they have complete octet (apart from Helium, which has duet) , hence they are highly stable on their own and do not react with others to form compounds in standard temperature and pressure conditions.

Why electron gain enthalpy of noble gas is positive?

The noble gases present in the group 18 of periodic table, have electronic configuration ns2np6. ... Thus, in case of noble gases, where it resists the addition of electrons, extra energy is required in order to force the electron to bind to the stable atom. Therefore, making the electron gain enthalpies positive.

Why chlorine has highest electron gain enthalpy?

Among the 4 halogen atoms mentioned above, the atom element which will have a greater value of electron gain enthalpy will be chlorine. ... But, chlorine is large in size and has comparatively low value of electronegativity than fluorine. Thus, it accepts an electron easily and has the highest electron gain enthalpy value.

Which has highest polarizability?

The idea is that the atom that is the least electronegative AND the largest radius is the most polarizable. This happens to be the lower left of the periodic table. Smaller electronegativity means it does not want to pull electrons towards itself as easily.

Which has higher polarizability?

The biggest factor that effects the polarizability of a substance is the size of the material. Larger molecules, atoms, or ions are more polarizable than smaller objects.

Are noble gases polarizable?

The attractive force INCREASES with the size of the atom as a result of an INCREASE in polarizability and thus a DECREASE in ionization potential. Overall, noble gases have weak interatomic forces, and therefore very low boiling and melting points compared with elements of other groups.

Which hydride has lowest boiling point?

Hence, among group 15 hydrides, phosphine has the lowest boiling point.

Which will have highest boiling point?

The chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten.

What is the electron gain enthalpy of noble gas?

Answer: Electron gain enthalpy values of noble gases are positive because they have stable electronic configuration and thus have no tendency to take additional electron.

Why second gain enthalpy of oxygen is positive?

Now when another electron is added to O− it will form an O2− ions and energy is absorbed to overcome the strong electrostatic repulsion between the negatively charged O− ion and the second being added. Thus the second electron gain enthalpy of oxygen is positive (as the energy is absorbed).

Why electron gain enthalpy of nitrogen is zero?

Since the electronic configuration of nitrogen is 2s2 2p3, it has a half filled p shell which is a stable configuration. Thus, it has a relatively low tendency to gain or lose electrons and its electron gain enthalpy is zero.

Why zinc is not a noble gas?

A valence subshell is one which can react to form a bond. That's why zinc is not a noble gas – the 4p orbitals count as valence (reactive) orbitals for zinc even while the 4d don't. ...

Can noble gases exist alone in nature?

In nature the atoms of noble gases do not bond either with other gases or with each other. Some of the larger noble gases can be made to form molecules. ... This does not normally happen in natural conditions.
