2nd one, if the have similar properties that repeat to the next period, it's the same as saying they are in the same group, which are the up and down rows, and those are of similar properties, ex the noble gases, the halogens....

well the periods aren't the same as the groups.. does this still mean it's the second one?

I ment if you take H then go across to the next period, you have Li, go to the next period again you have Na..by going to the next period (across), you are essentially listing the group of elements (up and down)
