and 5, Sections 1.5,
13.1
To predict how changes in the numbers
of protons, electrons, or both affect the
size of the resulting atom or ion, and to
deduce the relative sizes of atoms from
their positions in the periodic table

Sections 5.1, 5.4, 5.5
Section 13.4
Sections 5.4, 5.5
13.2
To deduce the relative ionization
energies of different elements from their
positions in the periodic table, and to
distinguish (1) a combination of
ionization energy and electron affinity
of two elements from (2) the energy of
reaction of the elements in their
standard states

13.3
To use electronegativity differences to
predict the bond types between atoms of
the elements
13.4
To deduce the shape of a molecule or a
polyatomic ion from its electron dot
diagram
13.5
To deduce the polarity of a molecule
from the orientations of its polar bonds
13.6
To show how the three intermolecular
forces affect the properties of substances
