Only 17 and 18.
Colunms are named 'Groups'. Rows are named 'Periods'.
They follow a pattern for valence electrons.
The elements in columns 3 through 12 on the periodic table are known as the transition metals. These elements are characterized by their ability to form multiple oxidation states and exhibit metallic properties like high electrical conductivity, luster, and malleability. They play important roles in various industrial applications and biological processes.
It is called a Group. There are 18 groups in the modern periodic table.
The columns are called groups (or, sometimes, families). The rows are called periods.
The periodic table contains seven rows of elements. The lanthanide series belongs to row six as elements 57-71. The actinide series belongs to row seven as elements 89-103.
Periodic table contains elements arranged in rows and columns. It is done according to increasing atomic number.
There are 18 groups in the Periodic Table of elements.

Representative elements
There are 18 groups in the periodic table of elements.
The 18 columns on the periodic table are called groups or families. Each group contains elements with similar chemical properties due to their shared number of valence electrons.
The vertical columns.
The vertical columns on the periodic table are called groups or families. Each group contains elements with similar chemical properties due to their shared number of valence electrons.
The columns of elements on the periodic table are called groups. Each group contains elements with similar chemical properties due to their shared number of electrons in the outermost energy level.
