michael CHM 1045 (Post Lecture Homework Chapter 08 lonization Energy I Review | Constants Pe lonization energy (E) is the amount of cnergy required to remove an electron from a neutral gaseous alom or gaseous ion. Electrons are attracted to the positively charged nucleus; therefore removing an Part A electron requires energy. The process is cndothemic, and so ionization encrgies have a positive value. The first ionization energy ( Eu) is the energy Hssociated with the removal of an electron trom the neutral gasecus atom. The reaction is represented for the generalized atom X as Based on position in the periodic table and electron configuration, Hirange thesc clements ader of decreasing En Rank the elements from highest to lowest ionization energy. To rank items as equivalent, overlap them. X-X++e • View Available Hint(s) The amount of energy required to remove an electron is related to the effective nuclear charge and the stability of the electron cmligutation of the atom It therefore shows penodic variation generally increasing from left to right in a period and from bottom to top of a group.
