Unformatted text preview: Trends in the periodic table: Trends in the periodic table: Ionization Energy Ionization Energy Atomic Radius Atomic Radius Electron Affinity Electron Affinity Electronegativity Electronegativity Background Background Electrons can jump between shells (Bohrs model supported by line spectra) The electrons can be pushed so far that they escape the attraction of the nucleus Losing an electron is called ionization An ion is an atom that has either a net positive or net negative charge Q: what would the charge be on an atom that lost an electron? Gained two electrons? A: +1 (because your losing a -ve electron) A: -2 (because you gain 2 -ve electrons) Ionization energy Ionization energy Ionization energy is the energy required to remove one outer electron from an atom We will be examining the trends in ionization energy in groups and periods Handout Note: atomic radius is the distance from the nucleus to the outer electron shell Follow directions on sheet and answer questions (you can use textbook for help) Ignore H when looking at trends, look at many periods/groups when summarizing trends Periodic table trends Periodic table trends Answers Answers Ionization energy vs. atomic numberIonization energy vs....
