What kinds of predictions did Mendeleev make using his table?
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.
Who attempted to classify the elements by organizing them into a seven column table?
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.
What property did Medeleev position the elements?
Mendeleev positioned the elements primarily based on their atomic mass and their chemical properties. He arranged them in a periodic table format, grouping elements with similar properties into columns, which allowed him to predict the existence and properties of undiscovered elements. This arrangement highlighted the periodic trends in element behavior, demonstrating that properties recur at regular intervals when elements are ordered by increasing atomic mass.
Which elements have similar chemical properties in sulphur and helium?
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
Why are the elements grouped on the periodic table of 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.
Which grouping indentifies chemical properties?
The group. Elements in the same group tend to have similar properties.
What is a period on the periodic table and how does it help organize the elements?
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.
What is a period or series?
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.
How did Mendeleyev organize the periodic table of elements?
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.
What kinds of predictions did Mendeleev make using his table?
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.
What method did mendeleev use to organize the element?
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.
Who attempted to classify the elements by organizing them into a seven column table?
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.
Elements in a column are called . These elements have similar chemical and physical properties.?
These elements have similar chemical and physical properties.

Which elements have similar chemical properties in sulphur and helium?
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
How did Dmitri Mendeleev set up the periodic table by?
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.
What is grouping similar objects called?
Grouping similar objects is called classification or categorization. It involves organizing items based on shared characteristics or properties to facilitate understanding and organization.
