The Periodic Table organizes elements according to the nature of their valence levels. The number of electrons needed to complete the valence level largely determines the chemical behavior of the element. Within groups or columns, the elements will have similar chemical properties. The elements go from more to less active from left to right, with the column on the far right containing those elements that are considered inert, or not chemically active normally.
periodic table of elements
Groups are arranged as columns in the periodic table; the contained elements have similar properties.
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
It groups together elements with similar properties.
There are 18 groups in the periodic table of elements.
Both arrange elements in groups of elements having similar properties.
Both arrange elements in groups of elements having similar properties.
The elements with similar properties are placed in groups. Periodic table contain 18 groups.

It groups elements with similar properties in vertical columns
The properties of chemical elements have a periodic trend.
The elements are organised in the periodic table of elements by order of ascending atomic number. They are arranged in groups and periods to demonstrate the gradual trends that are characteristic of certain groups of elements.
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
It groups together elements with similar properties.
The periodic table organizes the elements so that they are easy to find and it also puts them into groups or "families" of elements with similar traits.
