• Ionization energy is defined as the energy required to
• Think of ionization energy as a
measure of how ____________ an atom’s nucleus holds onto its electrons.
A low ionization energy indicates that
the atom has a ____________ hold on its electrons – and vice versa.
Does the group trend for ionization energy make sense?
Does the period trend for ionization energy make sense?
Back to the question: why are alkali metals so
reactive?Consider: what do all thing in the physical universe want?
OCTET RULEAtoms tend to gain, lose, or share electrons to acquire a full set of _______ valence electrons.________ IS GREAT!(except those close to helium, like _____________ & _____________ who only want ______ electrons)
• Do metals have high or low ionization energies?
Will it be easier for metals to gain or lose electrons to attain a noble gas
configuration?
METALS REACT BY
______________ELECTRONS!!The lower the ionization
energy, the __________ it is for a metal to lose electron(s), and
the ______________ reactive the metal is!
