Solution Summary: The author explains that the element with the largest atomic radius should be selected from the P, As and S.
The element with the largest atomic radius should be selected from the P, As and S.
Concept introduction:
From left to right across a period atomic size get decrees. From top to bottom across a group atomic size increase.
Interpretation Introduction
(b)
Interpretation:
The one with the smallest radius should be selected from Xe, O2-, N3- and F-.
Concept introduction:
From left to right across a period atomic size get decrees. From top to bottom across a group atomic size increase.From left to right across a period atomic size get decrees. From top to bottom across a group atomic size increase.
Generally, adding electrons to atom to produce anion, increases it size. While removing electrons from atom to produce cation decrease it size.
Interpretation Introduction
(c)
Interpretation:
The one with the highest difference between 1st and 2nd ionization energy should be selected from Al, Si, P and Cl.
Concept introduction:
Ionization energies generally increase from left to right across the period and decreasing from top to bottom within a group.
Interpretation Introduction
(d)
Interpretation:
The one with the largest ionization energy should be selected from C, Si and Sn.
Concept introduction:
Ionization energies generally increase from left to right across the period and decreasing from top to bottom within a group.
Interpretation Introduction
(e)
Interpretation:
The one with the largest electron should be selected from Na, B, Al and C
Concept introduction:
Move across a row in the periodic table, from left to right the values of the electron affinities become more negative and move across up a column, the values of electron affinities become more negative.
These are in the wrong boxes. Why does the one on the left have a lower molar mass than the one on the right?
SYNTHESIS REACTIONS. For the following reactions, synthesize the given products from the given reactants.
Multiple reactions/steps will be needed. For the one of the steps (ie reactions) in each synthesis, write out the
mechanism for that reaction and draw an energy diagram showing the correct number of hills and valleys for
that step's mechanism.
