	List -I (Atomic number)		List II (Group number and period number)
A)	56	I)	9,4
B)	50	II)	3,6
C)	27	III)	14,5
D)	58	IV)	2,6

 

• A. A - III, B-IV, C-I, D-II
• B. A-II, B-III, C-IV, D-I
• C. A-IV, B-I, C-II, D-III
• D. A-IV, B-III, C-I, D-II

Answer 1

The Correct Option is D

To solve the problem, we need to match atomic numbers with their respective group and period numbers from the periodic table.

1. Identifying the Elements:

• A) 56: Atomic number 56 is Barium (Ba) — an alkaline earth metal.
  It belongs to Group 2, Period 6.
• B) 50: Atomic number 50 is Tin (Sn) — a p-block element.
  It belongs to Group 14, Period 5.
• C) 27: Atomic number 27 is Cobalt (Co) — a transition metal.
  It belongs to Group 9, Period 4.
• D) 58: Atomic number 58 is Cerium (Ce) — a lanthanide.
  It is placed in Group 3, Period 6.

2. Matching with List II:

• A → IV → (2, 6)
• B → III → (14, 5)
• C → I → (9, 4)
• D → II → (3, 6)

Final Answer:
The correct matching is: A – IV, B – III, C – I, D – II
