What two very special things are named after Dmitri mendeleev?
The periodic table of elements is named after Dmitri Mendeleev for his foundational work in organizing the elements. Additionally, an element, atomic number 101, is named mendelevium in his honor.
Who is Dmitri mendeleev's daughter?
Dmitri Mendeleev did not have a daughter. He had two daughters, Olga and Lyubov, with his first wife Feozva.
Mendeleev's pattern repeated after how many elements?
Mendeleev's pattern repeated after every 8 elements.
What was Mendeleev able to find out for each element?
Dmitri Mendeleev was able to determine the atomic mass and properties of each element, as well as predict the existence and properties of undiscovered elements based on the periodic patterns he observed in their properties. He arranged the elements in his periodic table in order of increasing atomic mass to demonstrate their recurring chemical and physical properties.
What two elements in the fifth period violate the original periodic law as stated by Mendeleev?
THse elements are tellurium and iodine.
What two very special things are named after Dmitri mendeleev?

Who is Dmitri mendeleev's daughter?
Dmitri Mendeleev did not have a daughter. He had two daughters, Olga and Lyubov, with his first wife Feozva.
What elements did Dmitri mendeleev discover?
In 1869, a total of 63 elements had been discovered by. A few were gases. Two were liquids. Most were solid metals.
What are the names of two pre-20th century scientists?
Humphrey Davy, Dmitri Mendeleev.
Who is credited with the creation of the first periodic table?
Dmitri Mendeleev is credited with the creation of the first periodic table in 1869. He organized the elements based on their atomic mass and chemical properties, leaving gaps for undiscovered elements that were later found to fit his predictions.
What were the two main themes that mendeleev developed while writing his textbook the principles of chemistry?
Dmitri Mendeleev's two main themes in his textbook "The Principles of Chemistry" were the periodic law and the organization of elements into the periodic table based on their atomic weights. He also emphasized the relationships between the properties of elements and their positions in the periodic table.
Who was the first person to publish a periodic table?
Dmitri Mendeleev is credited with publishing the first widely recognized periodic table of elements in 1869. He organized the elements based on their atomic mass and predicted the properties of missing elements, allowing for future discoveries.
What were the names of the two men credited with the development of the first periodic table?
Dmitri Mendeleev and Lothar Meyer
Who were the two men credited with the development of the first periodic tables in 1869?
Dmitri Mendeleev and Lothar Meyer
Mendeleev combined the ideas of two earlier scientists who were these scientists and what did they do?
The two earlier scientists whose ideas Dmitri Mendeleev combined were Antoine Lavoisier and John Dalton. Lavoisier established the law of conservation of mass, while Dalton introduced the atomic theory by proposing that all matter is composed of atoms. Mendeleev built upon these concepts to develop the periodic table of elements.
What are the two especially important properties that Dmitri mendeleev noted about the elements?
Dmitri Mendeleev noted that elements displayed periodicity in their properties, with similar properties occurring at regular intervals when elements were arranged in order of increasing atomic mass. He also recognized that there were gaps in the sequence of known elements, which led him to predict the properties of undiscovered elements.
Mendeleev's pattern repeated after how many elements?
Mendeleev's pattern repeated after every 8 elements.
