Answer
a) From left to right atomic radius decrease
b) From left to right density increases
c) From left to right ionization energy increases
d) From left to right standard oxidation potential decreases
Work Step by Step
a) Atomic radius increases due to an increase in effective nuclear charge
b) Density increases due to the increases in atomic mass and decrease in atomic radius
c) Ionization energy increases due to the higher effective nuclear charge
d) Standard oxidation potential decreases because higher effective nuclear charge
