Its atomic #/mass is what determines an elements place on the table. the lower the number, the lighter the element and also the higher it is on the periodic table.
The periodic table is arranged in groups that go left to right. The elements on the Left have valence shells that are not full (group 1). The farther you move to the right, the the valence shell on the element are filled up. This is why the noble gasses are in the last group (18). Their valence shells are full and make them un reactive.
You should read this, it has a lot of good information that you will probably need:

On the second one, I believe it decreases although I'm not 100% sure.
