Periods: The properties of the elements are a periodic functions of their atomic number. This means if you arrange them by atomic number and place them side by side you would start a new row when a property pops up that you've already seen.
Sooooo.....how many rows are there on the Periodic Chart?
(don't let those two rows at the very bottom fool you; the are supposed to fit into rows 6 and 7 but then we wouldn't be able to put charts on the wall or in our notebooks. They are at the bottom just to shorten things up a bit).

"The periodic table of the chemical elements is an arrangement of the elements ordered by atomic number in columns (groups) and rows (periods) so as to emphasize their periodic properties."
