(a)
Interpretation:
From the given pair which has larger atomic radius has to be predicted.
Concept Introduction:
Periodic properties
In column the ionic radii or atomic radii is always increases, as the
In period the ionic radii or an atomic radius is always decrease due to the nuclear charge increases.
When going across a period, the cations decrease in radius.
The distance from centre of nucleus to the valence shell electron of an atom or ion is called atomic or ionic radius.
(b)
Interpretation:
From The given pair which has higher ionisation has to be predicted.
Concept introduction:
Periodic properties
In column the ionic radii or atomic radii is always increases, as the atomic number and the size of the atom gets larger.
In period the ionic radii or an atomic radius is always decrease due to the nuclear charge increases.
When going across a period, the cations decrease in radius.
The distance from centre of nucleus to the valence shell electron of an atom or ion is called atomic or ionic radius.
