What conditions will cause a redox reaction to be nonspontaneous

The sum of the voltages of the oxidatiin and reduction half-reactions is negative.

What periodic trend does the atomic radius follow

The atomic radius gets larger toward the bottom left of the periodic table. In general, the radius gets smaller as you go from left to right across the same period and the radius gets larger as you go from top to bottom down the same group.
