When was the periodic table created and who by?
The periodic table was created by Dmitri Mendeleev in 1869. He organized the elements based on their chemical properties and their atomic weights, creating a system that arranged the elements into groups and periods. This arrangement allowed for the prediction of missing elements and became the basis for the modern periodic table.
What later evidence proved that mendeleev was correct?
Later evidence that supported Mendeleev's periodic table included the discovery of new elements, such as gallium and germanium, which matched his predictions for their properties and placements. Additionally, the development of atomic theory and the understanding of atomic structure revealed that elements' chemical properties are related to their atomic number, aligning with Mendeleev's arrangement. The periodic law, which states that the properties of elements are periodic functions of their atomic numbers, further validated his work. These findings confirmed the periodic table's utility and accuracy in organizing elements.
How did mendelevium the element get its name?
The name of the chemical element mendelevium is derived from the name of the Russian chemist Dimitri Ivanovici Mendeleev, the discoverer of the periodic table of elements.
What did Dmitri mendeleev invent?
The Periodic Table of Elements
What was Mendeleev's prediction?
Professor Dmitri Mendeleev published the first periodic table of chemical elements in 1869 based on properties which appeared with regularity. He noted gaps in the table, and predicted that as-of-yet unknown elements existed with properties appropriate to fill those gaps.

What type of matter is found in the periodic table?
The periodic table contains all the known elements, which are the basic building blocks of matter. These elements are organized based on their atomic number, electron configuration, and chemical properties.
What is the chemical symbol for radium on the periodic table of elements?

How many elements the modern periodic table contains approximately?
The modern periodic table contains approximately 118 elements.
How many elements do a periodic table have?
It's 118 chemical elements in the periodic table.
What is the name of the period that contains americium?
Americium is a member of the actinoids family of chemical elements, period 7 of the periodic table of Merndeleev.
How many elements are listed on the periodic table that has symbols for them?
All the elements listed on periodic table has symbols for them.There are total 118 elements in periodic table.
What are the collums of the elements called on the periodic table?
The columns of elements on the periodic table are called groups. Each group contains elements with similar chemical properties due to their shared number of electrons in the outermost energy level.
How does the periodic table summarize elements?
In the periodic table chemical elements are orderd in periods and groups.
How many elements are on the periodic table 2013?
118 chemical elements are now in the periodic table.
Is HO4 part of the periodic table?
The Periodic table contains only elements, however, HO4 is a compound and hence has no place on the period table.
