How is the modern periodic table different from the first periodic table?
when the periodic table was first made, it only had the basic elements eg. hydrogen, oxygen, etc. Now with scientist finding more elements and creating them eg. americum, einstienium or europium, there are more elements than ever before. An element only has to exist for 2 seconds before they put it on the periodic table.
What country was the periodic table made in?
dmitri Mendeleyev was in a university in St.Petersburg Russia when he made the periodic table...hope this answers your question...jo_phil
Did the periodic table all ways looked this way?
no because if you look back in time more they didn't know as much as we do now so we learn more over time so if you looked back in time you wold see that there would be gaps in random spots on the periodic table. :)
Where is pg on the periodic table?
PG is not a recognized element on the periodic table. It may refer to various entities outside of the elements listed on the periodic table. Can you provide more context so I can offer a more precise answer?
Where is ammonia located on the periodic table?
Ammonia is a compound made of nitrogen and hydrogen, so it is not located on the periodic table.
Why does periodic table needs to be develop?
so that it will be acceptable in modern lives of the people in the world
What is the correct chronological order of scientists contributing to the modern periodic table?
Dmitri Mendeleev was the first to develop the modern periodic table in 1869. Later, Henry Moseley rearranged the elements by atomic number, which is the modern arrangement. So, Mendeleev comes before Moseley in terms of their contributions to the modern periodic table.
How many elements are in included in the modern periodic table?
112 elements are known, with the existence of addition 6 elements being tentatively proposed.
Why is the periodic table said to be periodic?
The name comes from the "periodic" (regularly arranged) traits of the material elements. The name given to the table's horizontal rows is periods.The Periodic Table is a tabular arrangement of the elements in increasing order oftheir atomic numbers, so that elements with similar properties are in the same column. There are 18 columns, called groups, and seven rows, which are called periods, in the modern periodic table.

Is carbon the first element in the periodic table?
NO!!! Carbon is No. 6 in the Periodic Table. Hydrogen is No. 1 in the Periodic Table.
Is copper wiring a mixture compound or element?
Copper is on the Periodic Table, anything on the periodic table is an element so copper wire is made from an element.
How could modern periodic law remove various anomalies of mendeleevs periodic table?
1.) The atomic mass in Mendeleev's periodic table does not increase regularly. therefore, it was impossible to predict the number of elements between two elements.The Modern periodic table has been made according to the increasing atomic number (Modern Periodic Law states that 'The properties of an element are the periodic function of its atomic number). The atomic number gives us the number of protons in the nucleus of an atom. the atomic number increases by one as we go from one element to the next. thus, this makes it easy to ascertain how many undiscovered elements may be there between two known elements.2.) Mendeleev's periodic table was made according to increasing atomic masses. we know that of an element have same chemical properties and atomic number, but different atomic masses. So, the concept of isotopes can not be satisfied.The Modern periodic table is according to increasing atomic numbers. Therefore, the problem of isotopes is easily dealt with.
Why is the table of elements named the periodic table?
The periodic table is named so because the elements are aligned in 'periods'. But it probably works the other way round. The Periodic Table has that name because it arises from Mendeleev's formulation of the Periodic Law, which he stated as "When the elements are arranged in order of increasing atomic weight, their chemical properties recur as a periodic function". The modern Periodic Law is the same except that "atomic weight" has been replaced with "atomic number".
Where is iron oxide on the periodic table?
Iron oxide is not on the periodic table because it is a compound and the periodic table is only for elements.The elements that make up iron oxide (iron and oxygen) can be found on it however.Iron is near the top and middle of the periodic table and has the symbol Fe.Oxygen is near the top-right corner and has the symbol O.
Is cottage cheese on the periodic table?
No, cottage cheese is not on the periodic table. But I did laugh when I saw that, so thank you
