What is the long form of modern periodic table?
Long Form of Periodic Table. The modern or long form of the periodic table is based on the modern periodic law. The table is the arrangement of elements in increasing order of their atomic numbers. The modern periodic table is the present form of the periodic table.
What is difference between long form and modern periodic table?
No, there are no difference is the long form of periodic table and modern periodic table. – The first concept of periodic table was given by Mendeleev.
Why is the modern periodic table called long form?
The Modern Periodic Table is called as “long form” of the periodic table,since in comparison to Mendeleev’s Periodic table,it is longer and have the capacity to not only accommodate those elements which have been discovered but also which are yet to be discovered.
Who developed the long form of modern periodic table?
Bohr
According to Moseley, similar properties recur periodically when elements are arranged according to increasing atomic number. Therefore Bohr is the scientist who discovered the long form of the periodic table.
What is long form of periodic table and what are the structural feature of long form of the periodic table?
Long form of periodic table consists of horizontal rows and vertical columns. Horizontal row is termed as period while vertical column is called group. Periods: The long form of the periodic table consists of total seven periods.
What is the modern periodic table Class 11?
Modern periodic law states that physical and chemical properties of the elements are periodic function of the atomic numbers i.e.if the elements are arranged in order of their increasing atomic numbers, the elements with similar properties are repeated after certain regular intervals.
What is long form of periodic table give its advantages and defects?
Both Lanthanoids and actinoids are placed in separate panel at the bottom of the periodic table. Advantages of long form of periodic table: It gives a suitable link between the position of element and its electronic configuration. On the basis of atomic numbers it easier to remember all the elements.
Which is the main difference between Mendeleev periodic table and long form of periodic table?
| Mendeleev’s Periodic Table | Modern Periodic Table |
|---|---|
| 1. It is based on atomic mass. 2. It has 8 groups and 7 periods. 3. No place for isotopes. | 1. It is based on atomic number. 2. It has 18 groups and 7 periods. 3. Isotopes have a place. |
What is another name for the periodic table?
The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties.
How many groups are on the PTE?
eighteen groups
There is eighteen groups on the periodic table in total, and each periodic table group contains elements with the same number of valence electrons.
Who prepared modern periodic table Class 10?
Henry Moseley put forward the Modern Periodic table. He put forward the modern periodic law which states that the properties of elements are the periodic functions of their atomic number.
What is modern periodic law class 10?
The modern periodic law states that the physical and chemical properties of the elements are the periodic functions of their atomic numbers. Scientists arranged elements in increasing order of their atomic numbers from left to right across each row.
