Applying Concepts

These questions test conceptual learning.

These questions refer to the graph below.

(a) Based on the graphic data, ionization energies __________ (decrease, increase) left to right and __________ (decrease, increase) top to bottom on the periodic table.

(b) Which element has the largest first ionization energy?

(c) A plot of the fourth ionization energy versus atomic number for elements 1 through 18 would have peaks at which atomic numbers?

(d) Why is there no third ionization energy for helium?

(e) What is the reason for the large second ionization energy for lithium?

(f) Find the arrow pointing to the third ionization energy curve. Write the equation for the process corresponding to this data point.
