Solution: Explain the variation in ionization energies of carbon, as displayed in the graph.

Problem

A line graph has ionization number on the X-axis, ranging from 1 to 6 with intervals every 1, and ionization energy of carbon (kilojoules per mole) on the Y-axis, ranging from 10,000 to 50,000 with intervals every 10,000.  Data are summarized approximately as follows: An ionization number of 1 correlates with an ionization energy of carbon of 2000 kJ/mol; an ionization number of 2 correlates with an ionization energy of carbon of 2500 kJ/mol; an ionization number of 3 correlates with an ionization energy of carbon of 5000 kJ/mol; an ionization number of 4 correlates with an ionization energy of carbon of 7000 kJ/mol; an ionization number of 5 correlates with an ionization energy of carbon of 38000 kJ/mol; an ionization number of 6 correlates with an ionization energy of carbon of 48000 kJ/mol.

Explain the variation in ionization energies of carbon, as displayed in the graph.
