Question

In long form of periodic table an element 'X' is present in group 'Y' in which Mn is also an element. X, Y respectively are

• A. Bh, 7
• B. Bh, 8
• C. Hs, 7
• D. Hs, 8

Hint:

Transition groups: Mn in 7 (VIIB). Superheavy elements follow the same groups. Use IUPAC numbering. Confirm with electron configurations.

Answer 1

The Correct Option is A

1. Manganese (Mn, Z=25) is in group 7 of the periodic table (IUPAC numbering for transition metals).
2. The long form places elements in groups based on electron configuration; group 7 includes Mn, Tc, Re, Bh.
3. Bohrium (Bh, Z=107) is the synthetic element directly below Re in group 7.
4. Hassium (Hs, Z=108) is in group 8, below Os.
5. Thus, X = Bh, Y = 7.
6. Therefore, the correct option is (1) Bh, 7.
