Ionization potential values of nobles gases decrease down the group with increase in atomic size. Xenon forms binary fluorides by the direct rection of elements.Identify the correct statement(s) from below.
Ionization potential values of nobles gases decrease down the group with increase in atomic size. Xenon forms binary fluorides by the direct rection of elements.Identify the correct statement(s) from below.
A
Only the heavier noble gases form such compounds
B
It happens because the noble gases have higher ionizaiton energies.
C
It happens because the compound are formed with electronegative ligands.
D
Octet of electrons provide the stable arrangments.
Text Solution
Verified by Experts
Having high ionization energy, inert gases do not form compounds. Inert gas compounds are hypervalent in nature. So no question of octet fill up through compound formation.

The atomic size of an element increases down the group while along a period, it tends to decrease. Explain.
There are certain properties of the elements which vary (increase or decrease) gradually in the same period or group with increase in atomic number. These properties of elements which show a regular gradation on moving from left to right in a period or from top to bottom in a group are called periodic properties. The recurrence of similar properties of elements after certain regular intervals when they are arranged in the increasing order of their atomic numbers is called periodicity valency, atomic/ Some of the properties such as ionic size, ionization enthalpies, electro-negativity, electron gain enthalpy, oxidizing/educing power, acid/base character etc. are directly related to the electronic configuration of the elements. On the other hand, there are some properties such as etc. which are indirectly related to the electronic configuration of the elements. The cause of repetition of similar electronic configuration of their atoms in valence shells after regular intervals melting points, density Down the group, the atomic/ionic radii, metallic character and valencing character increase whereas ionisation enthalpy and electronegativity decrease. Across a right, period from left to atomic/ionic radii and metallic character decrease whereas ionization enthalpy, electronegativity, non-metallic character and oxidizing power increase. In general, electron gain enthalpy decreases i.e., becomes less negative bottom in a group. Across a period from left to right there is an over all increase in the electron gain enthalpies (i.e., it becomes more negative). However most gases have positive electron gain enthalpies which do not show any regular trend. Which of the following has least ionization potential ?
