Answer:
c) Hydrogen position is uncertain in modern periodic table.
Explanation:
Nature of Hydrogen:
- Because hydrogen can act as an alkali metal (group 1) as well as halogens (group17), its location in the periodic table is ambiguous .
- The place of hydrogen in the periodic table is disputed due to its diatomic nature, just like halogens.
- It combines with sulphur, oxygen, and halogens to generate compounds with the same formula as alkali metals. Its valance shell has one electron.
- As a result, the position of hydrogen in the periodic table is unknown.
- It has a unique place at the top of the periodic table.
