ionization energy
amount of energy it takes to remove an electron from an atom
positive
is ionization energy always positive or negative?
larger
ionization energy gets ______ as you move up a column
larger
ionization gets _____ as you move across
inversely
ionization is ______ proportional to atomic radius
more difficult
the smaller an atom, the ______ it is to remove during ionization
the energy cost increases
as you remove more electrons, does the energy cost increase or decrease during ionization?
there is a massive energy barrier
what happens when a cation achieves a noble configuration in relation to ionization?
core electrons are significantly more difficult to remove
why is there a huge energy barrier with noble gases for ionization?
NO
can you remove more than one electron at a time for ionization?
Al(g)—>Al+(g)+e-, Al+(g)—>Al2+(g)+e-
what is the first and second ionization of Al (g)
gas
what state is the ionization and electron affinity process?
electron affinity
the opposite of ionization energy, adding an electron to a neutral atom in the gas phase
there is no definite trend, but tends to become more negative diagonally from bottom-left to up-right
what is the trend of electron affinity?
it can be positive or negative
what is the sign of electron affinity?
endothermic
positive EA is _____
exothermic
negative EA is ______
positive
______ EA is endothermic
negative
______ EA is exothermic
endothermic
noble gases are always endothermic or exothermic?
they have energy inside and do not want extra electrons
why are noble gases always endothermic?
exothermic
halogens are the most endothermic or exothermic?
halogens
______ are the most exothermic
they are 1 electron away from being stable
why are halogens the most exothermic?
