Explanation:
The position of hydrogen is unsatisfactory in Mendeleev's periodic table. It was placed with Cu, Ag Au ,etc. Hydrogen is a metal which shows resemblance with halogenslike Cl, F, etc and with alkali metalslike Na, K, etc. That is why no fixed position was given to hydrogen in Mendeleev's periodic table.
