How could Mendeleev make predictions about the properties of undiscovered elements?
Mendeleev arranged the known elements by increasing atomic mass and grouped elements with similar properties together. Gaps in the table indicated elements that were yet to be discovered. By observing the patterns in the properties of known elements within each group, Mendeleev was able to predict the properties of the undiscovered elements that would fill these gaps.
Mendeleev made the first periodic table around?
Dmitri Mendeleev created the first periodic table of elements in 1869. He arranged elements by increasing atomic weight and grouped those with similar properties together. Mendeleev left gaps for undiscovered elements and was able to predict the properties of these missing elements.
Why did mendeleev chose to order the known elements by mass?
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.
What elements did mendeleev group with lithium?
Mendeleev grouped lithium with potassium and sodium in his periodic table based on their similar chemical properties and valence electron configurations. He recognized that these elements belonged to the alkali metal group.
How did Dmitri Mendeleev figure out how to put the first periodic table together?
Mendeleev organized elements by their atomic mass and properties, arranging them in a table where elements with similar properties were grouped together. Gaps were left for undiscovered elements, allowing Mendeleev to predict the properties of these missing elements based on their position in the table. This led to the development of the first periodic table.
Is this true that mendeleev also grouped elements that had similar properties?
true
How did Mendeleev list the elements?
The most important principle was the listing in groups, after similar chemical or physical properties.

Who is the scientist that grouped elements into sets of three?
Newland, Moseley, , Dobereiner, Mendeleeff...
How did Dmitri Mendeleev figure out how to put the first periodic table together?

This led to the development of the first periodic table.
What is the difference between the periodic table and Mendeleev's table?
The periodic table is a chart that organizes elements based on their properties and atomic structure. Mendeleev's table was an earlier version of the periodic table that arranged elements by atomic weight and grouped them by similar properties. Mendeleev's table also left gaps for undiscovered elements, predicting their properties accurately.
What states Mendeleev's periodic table on page 126-127 in the Nelson Science Textbook of Grade 9 for Ontario?
The Nelson Science Textbook of Grade 9 for Ontario states that Mendeleev's periodic table on pages 126-127 includes elements arranged by increasing atomic mass and grouped with similar properties. Mendeleev left gaps for undiscovered elements and predicted the properties of these missing elements based on the pattern of the known elements.
What physical property did Mendeleev use to places the element in rows on the periodic table?
Mendeleev used the increasing atomic mass of elements to arrange them in rows on the periodic table. This allowed for elements with similar properties to be grouped together and for the gaps to be left for undiscovered elements.
How are the elements in the first periodic table arranged?
In the first Periodic Table by Mendeleev, he arranged the elements in the increasing order of their atomic masses and repeating properties.
