Out of atoms H and He one with smaller radius should be identified. Concept introduction: As one moves from top to bottom the shells expands and size increases, while it decreases as one move along the period because of gradual increases in effective nuclear charge. This in turn increases influence of nucleus on valence electron and shrinks the radius along the horizontal row.

Solution Summary: The author explains that out of atoms, one with smallest radius should be identified. As one moves from top to bottom the shells expand and size increases, while it decreases as one move along the period.
Definition Definition Number of protons in the nucleus of an atom. It uniquely identifies an element, as the number of protons determines the element's properties. The periodic table of elements is arranged based on increasing atomic numbers, allowing scientists to easily locate and study elements.

(a)
Interpretation Introduction
Interpretation: Out of atoms H and He one with smaller radius should be identified.
Concept introduction: As one moves from top to bottom the shells expands and size increases, while it decreases as one move along the period because of gradual increases in effective nuclear charge. This in turn increases influence of nucleus on valence electron and shrinks the radius along the horizontal row.
(b)
Interpretation Introduction
Interpretation: Out of atoms Cl , In and Se one with smallest radius should be identified.
Concept introduction: As one moves from top to bottom the shells expands and size increases, while it decreases as one move along the period because of gradual increases in effective nuclear charge. This in turn increases influence of nucleus on valence electron and shrinks the radius along the horizontal row.
(c)
Interpretation Introduction
Interpretation: Out of elements with atomic numbers 120, 119, 117 one with smallest radius should be identified.
Concept introduction: As one moves from top to bottom the shells expands and size increases, while it decreases as one move along the period because of gradual increases in effective nuclear charge. This in turn increases influence of nucleus on valence electron and shrinks the radius along the horizontal row.
(d)
Interpretation Introduction
Interpretation: Out of atoms Nb , Zn and Si one with smallest radius should be identified.
Concept introduction: As one moves from top to bottom the shells expands and size increases, while it decreases as one move along the period because of gradual increases in effective nuclear charge. This in turn increases influence of nucleus on valence electron and shrinks the radius along the horizontal row.
(e)
Interpretation Introduction
Interpretation: Of atoms Na− , Na and Na+ one with smallest radius should be identified.
Concept introduction: As one moves from top to bottom the shells expands and size increases, while it decreases as one move along the period because of gradual increases in effective nuclear charge. This in turn increases influence of nucleus on valence electron and shrinks the radius along the horizontal row.
A pdf file of your hand drawn, stepwise mechanisms for the reactions.
For each reaction in the assignment, you must write each mechanism
three times (there are 10 reactions, so 30 mechanisms). (A) do the work
on a tablet and save as a pdf., it is expected to write each mechanism
out and NOT copy and paste the mechanism after writing it just once.
Everything should be drawn out stepwise and every bond that is formed
and broken in the process of the reaction, and is expected to see all
relevant lone pair electrons and curved arrows.
