Elements with the most similar physical and chemical properties are found in the same group or column of the Periodic Table. Each group contains elements that share common characteristics, such as reactivity, electronegativity, and atomic structure. For example, the alkali metals in Group 1 are highly reactive and have similar properties, as do the noble gases in Group 18, which are known for their lack of reactivity.
The most important principle was the listing in groups, after similar chemical or physical properties.
The elements of the periodic table are grouped and organized together based on similar characteristics. These include their atomic number, chemical families (halides, noble gases, metals, gases, transition elements) and nuclear sizes, among other factors.
Elements cannot be grouped solely by physical properties because these properties can vary widely within a category, leading to inconsistencies. For example, metals, nonmetals, and metalloids exhibit diverse physical characteristics, such as boiling points, densities, and states of matter at room temperature. Additionally, elements may share similar chemical properties regardless of their physical characteristics, making chemical behavior a more reliable basis for classification, as seen in the periodic table. Thus, grouping by physical properties alone can overlook essential relationships and trends among elements.

Elements are grouped on the periodic table based on their atomic number, electron configuration, and recurring chemical properties. Groups (or columns) contain elements with similar chemical behaviors, often due to having the same number of valence electrons. Additionally, elements are categorized into metals, nonmetals, and metalloids based on their physical and chemical properties. These classifications help predict how elements will react with one another and their behavior in various chemical contexts.

The periodic table of elements consists of elements organized by their atomic number, symbol, and atomic weight. Elements are grouped into categories such as metals, nonmetals, and metalloids based on their physical and chemical properties. Each element has unique properties that determine its behavior in chemical reactions.
Mendeleev chose to order the known elements by mass because he observed that there was a pattern in the physical and chemical properties of elements when they were arranged by increasing atomic mass. This led him to develop the periodic table, where elements with similar properties were grouped together.
Non metals are grouped together because of their similar properties. They are placed in groups-15,16 and 17
Mendeleev arranged the known elements in a table based on their atomic mass and chemical properties. He grouped elements with similar properties together in columns, known as groups, and arranged them in rows based on increasing atomic mass. He left gaps for undiscovered elements predicting their properties.
