topic(s): ionization energy

questions [12 points; 2 points / question]

1. what is ionization energy ?

2. actually, there's usually more than "one ionization energy" - there's a 1 st ionization energy ; a 2 nd ionization energy ; a 3 rd ionization energy; etc. what do these terms mean ?

3. analyze data (see tab labeled "IE") by making a graph of the first ionization energy versus atomic number (i.e. number of protons). describe any pattern in the 1 st ionization energy as a function of atomic number in a ____ in the periodic table.

a. row

b. column

4. rationalize the trends in the 1 st ionization energy in a ___ in the periodic table based on Coulomb's law and the periodic trend in atomic size. recall, what the atomic number represents.

a. row

b. column
