|
increases

|
shielding effect?
|
decrease in size from left to right is less pronounced from pds towards the bottom
|
|
periodic trend
|
as u move across pd. size of cations: decreases, size of anions: decrease
|
|
as you down a group, ionization energy...
|
decreases
|
|
cation
|
+ ions (lost electrons)
always smaller than neutral atom from which thye r made; more protons than electrons |
|
as you go across a pd, ionization energy...
|
increases
|
|
ionization energy
|
amount of energy required to move the most loosely held electron
|
|
anion
|
(- ion) gained electrons
always larger then neutral original atom; more electrons than protons |
|
group trend
|
as u go down a group, size increases
(greater # occupied energy levels) |
|
