Know why atoms get larger as we go from top to bottom in a group and slightly smaller
as we move from left to right on the periodic table.
Ionization energy is the energy it takes to remove an electron from a gaseous atom or ion.
It decreases from top to bottom and increases from left to right on the periodic table.
Much the same trend is noted for electron affinity, the energy change that takes place
when an electron is added to a gaseous atom or ion. The trends depend on the size of the
atom or ion and its effective nuclear charge.
Oxidation numbers are bookkeeping numbers. Know the rules for assigning oxidation
numbers.

compounds, oxyacids, simple coordination compounds, etc.66 STEP 4. Review the Knowledge You Need to Score High
