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.
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.
In 1869 a major event in the history of chemistry occurred it was the?
In 1869, Dmitri Mendeleev unveiled the Periodic Table of Elements, a groundbreaking framework that organized known elements based on their atomic mass and chemical properties. This systematic arrangement not only highlighted periodic trends but also predicted the existence and properties of undiscovered elements. Mendeleev's work laid the foundation for modern chemistry, revolutionizing the way scientists understood elemental relationships and interactions.

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?
The chemical symbol for radium on the periodic table of elements is Ra.
How many elements the modern periodic table contains approximately?

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.
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.
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.
