They change with atomic number.
Each element in the same group (column) in the Periodic Table have around the same properties.
There are 18 periods in the periodic table. The periods are divided according to the chemical properties of elements. Elements in a group have similar properties.
Arrangement of elements according to their periodic function,that is their atomic properties
number
There are 18 families. They are made according to the properties of elements. So the elements in a group has similar properties.
The Periodic Table of the Elements, sometimes called just the Periodic Table, is the document in which elements are organized by their properties. It was created in 1869.
Groups of the Periodic Table of Elements.
The repeating pattern of elements of their properties is called periodicity. Elements are arranged according to same chemical properties.

according to the wights of the atoms and their properties.
according to their properties. metals, nonmetals, and metalloids
There are 18 families. They are made according to the properties of elements. So the elements in a group has similar properties.
Elements in the same group have similar properties. The groups are made according to the properties of elements. Elements in a group have an equal number of valence electrons.

Dmitri Mendeleev arranged the elements in periodic table according to increasing weight. He found their properties to be periodic when arranged in this pattern.
