Question

write a general statement describing the periodic trend in metal activitiy across a group (vertical column) of the periodic table?

Answer 1

You cannot go across a group, you can only go up and down a group.  You can go across a period, however.  

So, going up and down a group, the activity of the metal increases as you go DOWN in a group.  This is true for group 1 and 2 metals, but not so much for transitions because they are not very reactive to begin with.
