What is periodic table of element?
Periodic table contains elements arranged in rows and columns. It is done according to increasing atomic number.
How periodic table came about?
The first written copy of the Periodic Table of elements was made in [blank] by Dimitri Mendeleev (1834-1907). It was done through a great amount of research by Dimitri, he published a science textbook, and made several drafts of his periodic table. The first English version was made in 1891 based off of the 4th russion edition.
Why did it take 20 years for chemists to finally accept the periodic table?
Many modifications were done. Finally moseley's periodic table was accepted.
What scientists also proposed a periodic table about the same time as Mendeleev?
Unknown to Mendeleev, Lothar Meyer was also working on a Periodic Table. Although his work was published in 1864, and was done independently of Mendeleev, few historians regard him as an equal co-creator of the periodic table.
Where did Johann Wolfgang discover the periodic table of elements?
Firstly, he didn't discover it; the periodic table was invented. Secondly, he wasn't the one to invent it - although his work did contributem that was done by Gregor Mendeleev.

Why do you need to learn the periodic table?
The periodic table should be memorized because it will make you know the symbols without searching for them all of the time. If you are in school, it is very likely that you will be tested on the table.
How long did it take to construct the periodic table?
It's been worked on for many years, but is technically not done yet
Why is the Lanthanide and Actinide Metals are found under the periodic table?
This was done only save space. Because there are so many elements in each Group (Group IIIB)--numbering 14 each--the Periodic Table would be twice as wide than as we know it.
Which property of matter can easily be determined by looking at the periodic table?
Various chemical properties can be determined. It is done by estimation from position of element.
What makes up the halogen triad?
This refers to an old "history of science " topic around the work done prior to mendeleevs on Periodic Table. Elements were put in triads with similar properties. The halogen triad was chlorine, bromine and iodine. Pretty useless idea long term but a good start for people who came later.
When did Antoine Lavoisier invented the first periodic table?
LaVoisier did not invent a "periodic" table, he simply was one of the first to make a scientific list of elements, doing so in 1789 with Traité Élémentaire de Chimie . However, this list was not "periodic" in that he made no attempt to line them up by chemical qualities. When this was done by Mendele'ev about 100 years later, a major breakthrough in chemistry was achieved.
