1.) use the interactive periodic table to answer the following questions about ionization energy.
what is the first ionization energy (ie1) of sulfur (atomic number 16)?
write the expressions for the successive ionization energies of s (ie1 to ie7)?
plot the successive ionization energies of s (ie1 to ie7).
what trend is seen in this plot? how do you explain the change in slope associated with the ie7?
2.) use the interactive periodic table to answer the following questions about ionization energy. start by selecting the periodic table link on the upper right side of the page beneath the sf6 molecule. using the pull down menu at the bottom of the table, select ionization energy.
plot the first ionization energies (ie1) of the group 1 elements. what is the trend in ie1?
what trend do you think you will you see if you plot any other group? (check your prediction.)
compare the trend in ie1 to the trend in atomic radii. is there a connection?
3.)what is electron affinity? give a definition and illustrate it by showing the process for a gas phase atom.
