Who first gave the concept of periodicity?
The concept of periodicity was first introduced by Dmitri Mendeleev when he created the periodic table in 1869, which arranged the elements based on their atomic mass and properties. Mendeleev's table allowed for the prediction of the properties of undiscovered elements and is considered a landmark achievement in the field of chemistry.
Which discovery showed that Mendeleev was correct in organizing his table of elements according to properties?
The discovery of undiscovered elements with properties predicted by Mendeleev's periodic table (like gallium, germanium, and scandium) confirmed the accuracy of his organization. These elements filled gaps in the periodic table and established a pattern of periodicity that supported Mendeleev's initial insights.
. To categorize the elements what reactions did Mendeleev observe?
These are of course chemical reactions, for example oxydation.
What is mendeleev's quotation?
Dmitri Mendeleev's famous quotation is: "I saw in a dream a table where all elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper." This quote refers to the dream Mendeleev had where he visualized the periodic table of elements, which he later developed and organized based on atomic mass.
Who created the periodic law?
The periodic law was proposed by Dmitri Mendeleev in 1869. Mendeleev organized the known elements based on their atomic mass to create the first version of the periodic table.
When Mendeleev changed the layout of the table how was he able to figure this out?
Mendeleev believed and enunciated the law of periodicity of chemical properties for chemical elements.
What did mendeleev mean by periodicity of properties?
what he meant by it was it meant the same as periodic table.

What scientist published the modern periodic table how was this arranged?
This chemist was Dmitri Mendeleev in 1869; the arrangement is based on the law of periodicity.
What are Dmitri Mendeleev's discoveries except the periodic table are?
Periodic Principles Law of Periodicity Periodic Table of Toxic Elements These are three of the many discoveries Dmitri Mendeleev researched during his life (1834-1907).
How do the atomic numbers of the elements with in each of group 1 2 and 13-18 of the periodic table vary?
Mendeleev's Periodic Table -- the reason for periodicity -- is explained by the arrangement of the electrons around the nucleus. *Read your chemistry book* :D
What is it called when a repetition of properties occurs when elements are arranged in order of increasing atomic number?
The repetition of properties when elements are arranged in order of increasing atomic number is called periodicity or periodic law. This organization of elements into periods and groups on the periodic table allows for the prediction of an element's properties based on its position.
Which discovery showed that Mendeleev was correct in organizing his table of elements according to properties?
The discovery of undiscovered elements with properties predicted by Mendeleev's periodic table (like gallium, germanium, and scandium) confirmed the accuracy of his organization. These elements filled gaps in the periodic table and established a pattern of periodicity that supported Mendeleev's initial insights.
. To categorize the elements what reactions did Mendeleev observe?
These are of course chemical reactions, for example oxydation.
True or false mendeleev also grouped elements that has similar properties?
True. Mendeleev organized the elements into the periodic table based on their atomic weight and similar chemical properties. He noticed that elements with similar properties tended to occur at regular intervals, leading to the periodicity of the elements.
What pattern did Mendeleev arrange elements in?
Dmitri Mendeleev arranged the elements in his periodic table in order of increasing atomic mass and grouped elements with similar properties together. This arrangement helped him to identify periodic trends and predict the properties of undiscovered elements.
Why were the elements Ga Sc and Ge important to Mendeleev?
Mendeleev included gallium (Ga), scandium (Sc), and germanium (Ge) in his periodic table because they filled gaps in the sequence of known elements at the time and helped demonstrate the periodicity of their properties. These elements were crucial in showing the predictive power of Mendeleev's periodic table in suggesting the existence of unknown elements and their properties.
