Mendeleev managed to predict undiscovered elements by comparing two different elements Atomic Mass, that had a gap between them, and averaging there atomic mass for example: Mn _ Co if you dont know what the middle element is then by looking at the the atomic mass of Mn and Co you can work out roughly what its atomic mass is. Mn=55 and Co=59 so by adding them together and dividing by 2 you get 57 however Fe is in fact 56 but as you can see it was very close and this was how he would work out the atomic mass. He would also compare the properties of elements with similar atomic mass for example the alkaline metals such as lithium and sodium will react in the same way by doing this he could work out what a missing element would look, feel, react like etc.

What is the greatest triumph about mendeleev's periodic table?
Dmitri Mendeleev's greatest triumph with the periodic table was his ability to predict the properties of undiscovered elements. Gaps in the table led him to propose the existence of new elements with specific characteristics, which were later discovered and matched his predictions, confirming the validity of his periodic law.
Is it true or false that Mendeleev and other scientists were able to use the periodic table to predict the properties of undiscovered elements?
True. Mendeleev and other scientists used the periodic table to predict the properties of undiscovered elements based on their position in the table. This led to the successful discovery and confirmation of elements like gallium and germanium.
Who arranged the elements in the periodic table according to increasing weight?
Dmitri Mendeleev is credited with arranging the elements in the periodic table according to increasing weight. He also left gaps for undiscovered elements and predicted their properties, leading to the development of the modern periodic table.
Who developed your modern periodic table in 1869?
Dmitri Mendeleev is credited with developing the modern periodic table in 1869. He arranged the elements based on their atomic mass and chemical properties, predicting the properties of undiscovered elements. Mendeleev's table laid the foundation for the periodic table we use today.
The first periodic table of elements Mendeleev created contained only 70 elements.ng?
Mendeleev's first periodic table contained 63 elements. He left gaps for undiscovered elements and predicted their properties based on the patterns of the known elements around them. Mendeleev's table was later expanded to include more elements as they were discovered.

Who create the first periodic table?
Mendeleev developed the first periodic table and Mosely later modernized it.
Father of the periodic table?
Dmitri Mendeleev is known as the father of the periodic table. He developed the periodic table by arranging elements based on their atomic mass and chemical properties, establishing the foundation for the modern periodic table used today. Mendeleev's table had gaps for undiscovered elements, which were later found and filled, validating his organization of the elements.
Is it true or false that Mendeleev and other scientists were able to use the periodic table to predict the properties of undiscovered elements?
True. Mendeleev and other scientists used the periodic table to predict the properties of undiscovered elements based on their position in the table. This led to the successful discovery and confirmation of elements like gallium and germanium.
Why was Mendeleev's periodic table considered a good model?
Mendeleev's periodic table was considered a good model because it organized elements based on their atomic mass and properties, allowing for predictions of undiscovered elements and their properties.
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.
Who arranged the elements in the periodic table according to increasing weight?
Dmitri Mendeleev is credited with arranging the elements in the periodic table according to increasing weight. He also left gaps for undiscovered elements and predicted their properties, leading to the development of the modern periodic table.
What is the probable sequence in which the following clades of animals originated from earliest to most recent?
