1.	Why the position of hydrogen was not fixed in mendeleeve\'s periodic table.
Answer» Because hydrogen could easily losse one electron to form a poditive cation as well as it existed as diatomic molecule as group 17 elements Yea Because of Hydrogen \' s anamolous behaviour. It shows properties of both metal and non metal, it can do both lose and gain electrons . Because Mendeleev arranged the elements in terms of their increasing atomic masses as well as their similar chemical properties Because mendeeleev arrange the elements according to increase atomic masses that\'s why a correct position of hydrogen did not explain in mendeeleev periodic table
