(a)
Interpretation:
The elements, sulfur, chlorine and silicon has to be arranged in the decreasing order of atomic radius.
Concept Introduction:
Atomic radius is the distance between the atomic nucleus and outermost shell having electrons of an atom. From the atomic radius, the size of atoms can be visualized
Down the group, the principal quantum number increases and thus the size of orbital also increases which results in the increase in atomic radii.
Along the period, the valence electron is added to the same shell and thus attraction by the nucleus gets stronger. Therefore, atomic radii reduces from left to right in the periodic table.
(b)
Interpretation:
The elements, cobalt, titanium and chromium has to be arranged in the decreasing order of atomic radius.
Concept Introduction:
Refer to (a).
(c)
Interpretation:
The elements, zinc, mercury and cadmium has to be arranged in the decreasing order of atomic radius.
Concept Introduction:
Refer to (a).
(d)
Interpretation:
The elements, antimony, bismuth and phosphorus has to be arranged in the decreasing order of atomic radius.
Concept Introduction:
Refer to (a).
