Electrophoretic ity increases (because of increase in no. of shells which leads to screening effect on the electrons on the in the last orbital) and atomic radius increase too because of the increase in shells
i. Electropositivity decreases on moving from left to right in a period
Electropositivity decreases on moving from down to up in a group
ii.Atomic radius increases from left to right
Atomic radius increases down the group
Hope it helps :)
