Explanation:
Mendeleev could not determine the accurate position of the hydrogen atom in his table.
This is because hydrogen’s characteristics are very similar to halogens and alkali metals.
Other key limitations in Mendeleev periodic table were that the atomic number in the table was not shown increasing in a regular pattern and the symmetry of the table was also disturbed.
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. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals.
