Question 54

Match the LIST-I with LIST-II.

LIST-I (Family)LIST-II (Symbol)
A.Pnicogen (group 15)I.Ts
B.ChalcogenII.Og
C.HalogenIII.Lv
D.Noble gasIV.Mc


Choose the correct answer from the options given below :

Group-wise names used in the periodic table:

• Group 15 elements are called pnicogens (pnictogens).
• Group 16 elements are called chalcogens.
• Group 17 elements are called halogens.
• Group 18 elements are called noble gases.

Now locate each super-heavy element given in LIST-II:

Case 1: $$\mathbf{Mc}$$ (Moscovium) has atomic number $$115$$ and lies in Group $$15$$. Hence it belongs to the pnicogen family.

Case 2: $$\mathbf{Lv}$$ (Livermorium) has atomic number $$116$$ and lies in Group $$16$$. Hence it belongs to the chalcogen family.

Case 3: $$\mathbf{Ts}$$ (Tennessine) has atomic number $$117$$ and lies in Group $$17$$. Hence it belongs to the halogen family.

Case 4: $$\mathbf{Og}$$ (Oganesson) has atomic number $$118$$ and lies in Group $$18$$. Hence it belongs to the noble-gas family.

Therefore, the correct matching is:
A. Pnicogen   → Mc (IV)
B. Chalcogen → Lv (III)
C. Halogen   → Ts (I)
D. Noble gas → Og (II)

Thus the required option is:
Option B: A-IV, B-III, C-I, D-II
