-An element is placed in that group of periodic whose group number is equal to the number of valence electrons.
Metals are grouped together to the left of the Periodic table.
Elements with same property are grouped together. Property can be estimated by its position.

Mendeleev's periodic table arranged elements by increasing atomic mass and grouped elements with similar properties together. Today's periodic table is similar, but it is arranged by increasing atomic number, which reflects the number of protons in an atom's nucleus. Both tables also show periodic trends in properties as you move across and down the table.
The Bohr model helped explain the arrangement of electrons in an atom's energy levels. This model laid the groundwork for understanding the structure of the periodic table by showing that elements with similar electron configurations tend to exhibit similar chemical properties and are grouped together in the periodic table.
Metals are grouped together to the left of the Periodic table.
Some common questions about the periodic table include: What is the periodic table? How is it organized? What do the numbers and letters on the table represent? Why are some elements grouped together? How many elements are there in total?
Group are based on similar properties. The elements having same chemical properties are grouped together.
There are 18 groups in the Periodic Table of elements.
Elements with same property are grouped together. Property can be estimated by its position.
Periodic table show that elements have properties which are periodic in nature. These properties can be grouped together.
Properties of elements are periodic function of atomic number. Elements with same chemical properties are grouped together.
The elements with same properties need to be grouped together. So that it is easier to study the elements
Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
Some important questions to ask about the periodic table include: What is the organization of elements based on? How are elements grouped together? What are the properties of elements in the same group or period? How does the periodic table help predict the behavior of elements?
