Question

The position of hydrogen in the modern periodic table is not fixed.

• A. True
• B. False

Answer 1

The correct option is A

True

Hydrogen has properties similar to the group 1 elements (alkali metals) and it also shows the properties of group 17 elements (Halogens). Hydrogen's similarity with two completely different groups of elements in the modern periodic table has made it difficult for scientists to place it in particular group and hence the position of hydrogen in the modern periodic table is not fixed.
