Dobereiner was responsible for grouping element into triads. He grouped 3 element with same properties together.
By placing the elements in order of their Atomic Mass then grouping them based on similar chemical properties, Mendeleev recognized that there were gaps in the pattern he made where elements should be. He predicted there were some elements yet to be discovered and predicted their chemical properties. The elements he predicted were later discovered and named germanium, gallium, and scandium.
Johann Wolfgang Döbereiner attempted to classify elements by organizing them into a seven-column table, known as Döbereiner's triads, grouping elements with similar properties together.
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
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.
Mendeleev organized the elements in his table by increasing atomic mass and grouping elements with similar properties together. He left gaps in his table for unknown elements and accurately predicted the properties of these missing elements based on the patterns he observed.
The group. Elements in the same group tend to have similar properties.
A period on the periodic table is a horizontal row of elements that share similar properties. It helps organize the elements by arranging them in order of increasing atomic number and grouping elements with similar chemical properties together.
Periods and series are used when grouping elements. Elements are listed in rows, as periods, on the periodic table so that each is grouped with others with similar properties.
Mendeleev organized the periodic table of elements by increasing atomic mass and grouping elements with similar properties together. He left gaps in the table for undiscovered elements and predicted their properties based on the pattern of known elements.

Dmitri Mendeleev organized the elements based on their atomic mass, grouping similar elements together and leaving gaps for undiscovered elements. This led to the creation of the periodic table, where elements with similar properties were placed in the same column.
These elements have similar chemical and physical properties.
Johann Wolfgang Döbereiner attempted to classify elements by organizing them into a seven-column table, known as Döbereiner's triads, grouping elements with similar properties together.
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
Dmitri Mendeleev arranged the elements in the periodic table based on increasing atomic mass, while also grouping elements with similar properties together. This allowed him to identify patterns and gaps in the elements' properties, which led to the creation of a periodic law that predicted the properties of undiscovered elements.
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.
Grouping similar objects is called classification or categorization. It involves organizing items based on shared characteristics or properties to facilitate understanding and organization.
