Modern Periodic Table Class 10 / In the modern periodic table, elements are in order of atomic number in periods and groups.. # there are seven periods (horizontal rows) and 18 groups(vertical columns) in the modern periodic table. The modern periodic table : Modern periodic table contains 18 vertical column known as group and seven horizontal rows known as periods. Metals are found on the left side and centre of the modern periodic table. The modern periodic table consists of more elements when compared to the 63 elements in mendeleev's periodic table.
Atomic number is the basis for modern periodic table. Properties of elements are a periodic functions of their atomic number. Properties of groups and periods. The number of valence shell electrons increases with the increase in atomic number on moving from left to right in a period with each period marking the filling of a new electronic shell. It is also called as bohr, bury & rang, werner periodic table.

In 1913, an english physicist, henry moseley showed that the physical and chemical properties of the atoms of the elements are determined by their atomic number and not by their atomic masses. The periodic table is probably one of the most iconic scientific documents, a single table that holds within itself almost all chemical knowledge amassed by man. Atomic number is the number of protons in the nucleus, it is also equal to the number of electrons in the atom. #the 1st group elements are called alkali metals. ''properties of elements are periodic functions of their atomic numbers, i.e. Among halogens fluorine has the highest electronegativity of 4.0 than chlorine, bromine and iodine. Mendeleev discovered the modern periodic table in the year 1869.
