Numerous forms of Periodic Table have been devised from time to time. Some forms emphasise chemical reactions and valence, whereas others stress the electronic configuration of elements. A modern version the so called long form of the periodic tableof the elements, is the most convenient and widely used.
A periodic table is a tabular display of the chemical elements, organized on the basis of their atomic numbers, electron configurations, and recurring chemical properties. Elements are presented in order of increasing atomic number (number of protons). The standard form of table comprises an 18 × 7 grid or main body of elements, positioned above a smaller double row of elements. The table can also be deconstructed into four rectangular blocks: the s-block to the left, the p-block to the right, the d-block in the middle, and the f-block below that. The rows of the table are called periods; the columns of the s-, d-, and p-blocks are called groups.

Modern periodic table is invented by Henry Moseley.
Periodic table of elements.
In the modern form of periodic table, all elements are arranged in increasing order of their atomic numbers. The periodic properties of elements are functions of their atomic weights.
The modern periodic table is modified form of the mossleys periodic table,which was yet modifiied form of the mendileevs periodic table,which was based on the principle-atomic mass is the periodic function of the elements.Mossley changed the periodicity of elements to be the periodic functions of their atomic numbers.hence in the modern periodic table we can find,the repeatation of certain properties of elements after definite intervals and hence the periodic table has groups and periods the elements inside which,are similar.this is possible because across a period electrons increase by 1,keeping shells sama,and down a group,outer electrons remain same,but shells increase by1.
Yes.The modern periodic table is organized by atomic number. The elements properties are found to be periodic.
The modern long form of periodic table was constructed by Neils Bohr based on modern periodic law proposed by Moseley.
The modern long form version of the periodic table is now accepted by the IUPAC.
The modern long form of periodic table was constructed by Dmitri Mendeleev (1869).
There are 7 periods in the modern periodic table.
Modern periodic table is invented by Henry Moseley.
The modern periodic table has seven periods.
Periodic table of elements.
Modern periodic table is based on modern periodic law which states that physical and chemical properties of elemnts are periodic function of their atomic numbers.

Dmitri Mendeleev developed the modern periodic table in 1869.
In the modern form of periodic table, all elements are arranged in increasing order of their atomic numbers. The periodic properties of elements are functions of their atomic weights.
7 periods and 18 groups are there on the modern periodic table.
