Gallium which had the properties that Mendeleev predicted
DiscoVery of new elements
This scientist is the Russian chemist Dimitri Mendeleev.
Mendeleev's periodic table was confirmed to be useful because it accurately predicted the properties of elements that had not been discovered at the time. When new elements were discovered and found to fit into the gaps Mendeleev had left, it provided strong evidence for the effectiveness of his periodic table in organizing elements based on their properties. This confirmed the periodicity of elements and highlighted the power of the periodic table as a tool for understanding and predicting the behavior of elements.
When Mendeleev arranged the elements into the periodic table, he found that elements with similar chemical properties fell into groups on the table. These groups eventually became the columns we now refer to as families or groups. This organization allowed for predictability of element properties and led to the discovery of new elements.
The value of predicting the properties for gaps in Mendeleev's table was in providing a systematic way to identify missing elements and their properties based on the known trends of elements within the table. This predictive power allowed for the discovery and confirmation of new elements that filled the gaps, contributing to the organization and understanding of the periodic table.

Dmitri Mendeleev discovered the periodic law and created the first version of the periodic table of elements, organizing known elements by increasing atomic mass and predicting properties of undiscovered elements.
The discovery of germanium was important for Mendeleev's periodic table because its properties matched the gaps he had predicted in his table. This provided evidence for the periodicity of elements and the accuracy of Mendeleev's arrangement. Germanium's discovery also helped validate the periodic law which states that the properties of elements are periodic functions of their atomic numbers.
Mendeleev believed that the properties of elements were based on their atomic weight. He arranged the elements in his periodic table according to their atomic weights, which allowed him to predict the properties of missing elements. This led to the discovery of new elements and the development of the modern periodic table.
Dmitri Mendeleev is credited with developing the periodic table in a form close to its modern version. He arranged the elements based on their properties and left gaps for undiscovered elements, predicting their properties accurately. This work was inspired by his experience organizing playing cards into sets.
he was the man behind the discovery of periodic table according to the atomic numbers
Mendeleev used the properties of gallium, scandium, and germanium to predict their existence before they were discovered. Their discovery and properties helped confirm the accuracy of Mendeleev's periodic table and his periodic law. This further solidified Mendeleev's contributions to the development of the modern periodic table.
