CBSE Class 10 Answered

Why the position of hydrogen was not fixed in Mendeleev's periodic table  .
Asked by pdcavita | 29 Nov, 2017, 10:21: PM
answered-by-expert Expert Answer

 Hydrogen was not given a fixed position.

It was considered in Group IA as well as in Group VIIA, because it forms a positive ion as in HCl and a negative ion as in NaH.
