I believe the horizontal rows are called periods, and within the columns the chemical properties are the same or similar, repeating themselves across the periods. That is why they call it the periodic table.

The horizontal rows are called-periods-,there are seven -periods-and wthin the -periods-the chemical properties of the elements repeat themselves periodically across the table
The vertical rows are called families and the properties of the elements in a family are similar.

You should really do your own homework. Its different to ask a hard question but i know for a fact that you can find this information in any chemistry book and even the internet. Your just being LAZY

I believe you really need to read the chapter. It is not that difficult.
