I did not include the names of our atoms and I also did not include other elements usually found in two rows on the bottom. Now that's simply for simplification purposes. If you'd like to see the actual table, Google it or check out a chemistry textbook. Now these guys, these columns are known as groups. So group one, group two, group three, group four, all the way up to group 18, while these rows are known as periods. So period one, period two, period 3456, all the way up to period seven.
