The elements are put in order by atomic number (the number of protons in the nucleus) from least to greatest, and follow an observed pattern in atomic properties. As you follow a row (period) from right to left, the atomic properties slowly change from that of an Alkali Metal to that of a Noble Gas. This pattern is what makes up the periods on the Periodic Table. However, as we move along, there are sudden changes in atomic properties, from a Noble gas back to that of an Alkali Metal at the beginning of the period, and then the pattern starts over, slowly moving back towards the noble gasses at the end of each period. So, the rows are the pattern, shifting from Alkali to Noble, and each column is the group of all elements with certain properties (such as all Alkalis on the left, or all Noble gasses on the far right).

The columns of the periodic table bring together elements with similar properties.
Only in a two dimensional matrix (table) it is possible to show the periodicity of one 'variable' (chemical property / reactivity) of all elements.
A chart that displays and organizes the elements in rows and columns.
periodic table
The columns are groups or families, and the rows are periods.
The periodic table of elements lays out the elements in rows and columns. Rows are arranged so that elements with predictable characteristics or properties are in the same column.
It is true that periodic table is divided into rows and columns. The rows are called periods and columns are called groups.
