Who improved the periodic table?
Dmitri Mendeleev is credited with creating the first version of the periodic table in 1869. Mendeleev arranged the elements by atomic mass and predicted the properties of undiscovered elements. Subsequent scientists, such as Henry Moseley, contributed to refining and organizing the periodic table based on atomic number.
In what order did Mendeleev arrange the elements in the first periodic table?
Mendeleev arranged the elements in the periodic table according to their atomic masses.
Why were the elements gallium scandium and germanium important to Medeleev?
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.
Who made up the periodic table and what is he like?
The periodic table was created by Russian chemist Dmitri Mendeleev in 1869. Mendeleev was known for his meticulous and organized work ethic, as well as his ability to predict the properties of undiscovered elements through the development of the periodic table. He was also a teacher and published extensively on various scientific topics.
What do the long dashes represent on mendeleev's periodic table?
The long dashes on Mendeleev's periodic table represent gaps where elements had not yet been discovered but were predicted to exist based on the periodic pattern of elements. Mendeleev used these gaps to accurately predict the properties of the missing elements, leading to the discovery of new elements.
What was used by Mendeleev to organize his periodic table?
He organised the elements in the increasing order of the atomic mass.
How did chemists change Mendeleev's periodic table in early 1900s?
They used atomic number instead of Atomic Mass to organize the elements.
What characteristic of an element was used to organize the earliest periodic table?
Atomic mass was used to organize the earliest periodic table.
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.
What did Mendeleev use to create the periodic table?
what were the criteria used by Mendel in creating his periodic table
What characteristic was used to organize the first periodic table?
Mendeleev arranged the periodic table according to increasing atomic mass. This method has been used since he first developed it in the 1800s.
What is Dmitri Mendeleev's arrangement of elements called?
Dmitri Mendeleev's arrangement of elements is called the periodic table. He organized the elements based on their atomic mass and chemical properties, leading to the development of the modern periodic table used today.
Who improved the periodic table?
Dmitri Mendeleev is credited with creating the first version of the periodic table in 1869. Mendeleev arranged the elements by atomic mass and predicted the properties of undiscovered elements. Subsequent scientists, such as Henry Moseley, contributed to refining and organizing the periodic table based on atomic number.
Who the father of the periodic table as well as used his table to predict the discovery and properties of elements?
This scientist is the Russian chemist Dimitri Mendeleev.
What is the property used to organize the periodic table?
Atomic number
What periodic trends did Mendeleev organize his periodic table by Atomic number Atomic mass Octaves Triads First ionization energy?
In 1869, Mendeleev organized his periodic table by increasing atomic mass (atomic weight), using what is called the "law of octaves," by which every 8th element in the sequence shared similar properties. This was first observed by John Newlands in his element table around 1863.
In what order did Mendeleev arrange the elements in the first periodic table?
Mendeleev arranged the elements in the periodic table according to their atomic masses.
