Review • What is an ion? • An atom or molecule with a net electric charge due to the loss or gain of one or more electrons. • An ion is created when an atom loses an electron. • Removing one electron will result in the formation of a positive ion with a +1 charge.
What is Ionization Energy? • The energy required to overcome the attraction of the nuclear charge and remain an electron from a gaseous atom is ionization energy. • Ionization energy is used for predicting charges of ions. • The amount of energy required to remove the first outermost electron is the first ionization energy. • The amount of energy required to remove the outermost electron from the gaseous 1+ ion is the second ionization energy.
Factors in Ionization Energy • Attraction to the nucleus • An electron with a greater attraction to the nucleus increases the ionization energy. • Charge of the nucleus • If the nucleus contains more protons it will be positively charged, so electrons will have a greater attraction to it (vice versa). • Distance of the electron from the nucleus • The further away the electron is from the nucleus, the smaller the attraction will be.
Trends in Ionization Energy • The first ionization energy will gradually increase as you move from left to right across a period. • The first ionization energy will generally decrease as you move down a group on the periodic table. • The nuclear charge will increase, and the shielding effect is constant as you move across.
Bingo- Game 1 • Removing one electron results in the formation of a/an ________ ion with a charge of +1. • _______ is the energy required to overcome the attraction of the nuclear charge and gain an electron from a gaseous atom. • A/an _______ attraction of the nucleus for the electron leads to the increase in ionization energy. • When an atom loses an electron, it turns into a/an _______. • The nuclear charge increase and the _______ effect is constant as you move across. • The 1st ionization energy generally _______ as you move down a group of the periodic table. • The 1st ionization energy will gradually_______ as you move from left to right across a period. • _______is the energy required to remove the 1st outermost electron. • The concept of ionization energy is used _______. • _______ is the energy required to remove the outermost electron from the gaseous +1 ion.
Bingo-Game 2 • _______ is the energy required to remove the outermost electron from the gaseous +1 ion. • A/an_______ attraction of the nucleus for the electron leads to an increase in ionization energy. • The 1st ionization energy will gradually _______ as you move from left to right across a period. • The concept of ionization energy is used_______. • When an atom loses an electron it turns into a/an_______. • _______ is the energy required to remove the 1st outermost electron. • The nuclear charge increase and the _______ effect is constant as you move across. • _______ is the energy required to overcome the attraction of the nuclear charge and remain an electron from a gaseous atom. • The 1st ionization energy will generally _______ as you move down a group on the periodic table. • Removing one election results in the formation of a/an _______ ion with a +1 charge.
