Lesson 6: Arrangement of the Periodic Table


The elements on the periodic table are arranged so that their atomic numbers increase in order from left to right. There is a special name given to the horizontal rows on the periodic table. They are called periods. The first row, the one containing hydrogen and helium, is called the first period.

Groups of the periodic table (video) | Khan Academy


- Let's talk a little bit about groups of the periodic table. Now, a very simple way to think about groups is that they just are the columns of the periodic table, and the standard convention is to number them. This is the first column, so that's group one, second column, third group, fourth, fifth ...

Chem4Kids.com: Elements & Periodic Table: Periodic Table


The periodic table is organized like a big grid. Each element is placed in a specific location because of its atomic structure. As with any grid, the periodic table has rows (left to right) and columns (up and down). Each row and column has specific characteristics.
