transition elements
The elements that are listed in vertical columns all share specific aspects. These aspects include having the same number of valence electrons and having similar chemical properties.
they are called groups or families
The arrangement of all known elements in order of their atomic numbers is called the periodic table of elements. The periodic table organizes elements based on increasing atomic number, showing similarities in properties and periodic trends across rows and columns.
There are 18 columns (groups) and 7 rows (periods) in the periodic table, creating a total of 18 * 7 = 126 individual "boxes." Each box represents an element with unique properties and characteristics.
Group 7 in the periodic table is also known as the halogens.

The vertical columns are known as the groups. Elements in a given group have the same number of valence electrons and hence similar properties.

This is probably a reference to the periodic table of the elements, which has columns. All the elements in a given column have the same configuration of valance electrons. There is a column of noble gases, a column of halogens, etc.
The name comes from the "periodic" (regularly arranged) traits of the material elements. The name given to the table's horizontal rows is periods.The Periodic Table is a tabular arrangement of the elements in increasing order oftheir atomic numbers, so that elements with similar properties are in the same column. There are 18 columns, called groups, and seven rows, which are called periods, in the modern periodic table.
The elements between group 2 and 13 are called Transition elements. They are placed in center of periodic table.
On the Periodic Table, horizontal rows are given the technical term "periods", while vertical columns are called "groups". Elements in the same period are similar in that they have the same number of energy levels.
