A column is a chemical family, and they are split up into 18 families. An example would be column 1 which is the Alkali Metals and column 18 is the Noble Gases. A column also shares chemical properties with the elements in its group. A row is split up into groups of chemicals, and are ordered by the atomic number.
A horizontal row is called a period .
No. The horizontal rows of the periodic table are called periods. The vertical columns are called groups, and sometimes called families.
As with any grid, the periodic table has rows running left to right, and columns running up and down. The rows are called PERIODS and the columns are called GROUPS.
Whereas the vertical columns on the periodic table are called "groups", and represent the number of electrons in an element's outermost electron shell (eg. group 2 elements have twoelectrons in their farthest energy level), the horizontal rows, known as "periods", refer to the number of energy shells surrounding the nucleus of an element.
The columns are called groups (or, sometimes, families). The rows are called periods.
It is true that periodic table is divided into rows and columns. The rows are called periods and columns are called groups.
periods are the rows and families are the columns
The periodic table has 7 rows and 32 columns.
There are NO vertical ROWS, because rows run horizontally, and COLUMNS run vertically. There are 18 vertical columns in the periodic table.
A horizontal row is called a period .
Horizontal rows in Periodic Table are called Periods
The vertical columns in a periodic table are called Groups.
No. The horizontal rows of the periodic table are called periods. The vertical columns are called groups, and sometimes called families.
Groups or families are the vertical columns on the periodic table. Periods are the horizontal rows on the Periodic Table.

Periodic Table is expressed as rows and columns. It is used by locating the position of element.
