To match the given terms with their correct responses, we need to understand the definitions and characteristics of each term. Let's break down each option:
(1) Valency: The combining capacity of an atom
(2) Metals: Losses electron to become stable
(3) Non-metals: Gains electron to become stable
(4) Noble gases: They have stable configuration
Now let's match each term with its correct response:
A: 1-C, 2-B, 3-D, 4-A - Incorrect
B: 1-B, 2-D, 3-A, 4-C - Incorrect
C: 1-D, 2-A, 3-C, 4-B - Incorrect
D: 1-A, 2-C, 3-B, 4-D - Correct
Therefore, the correct matching is:
(1) Valency - A: Combining capacity of an atom
(2) Metals - C: Losses electron to become stable
(3) Non-metals - B: Gains electron to become stable
(4) Noble gases - D: They have stable configuration
So, the correct answer is D.

Understanding Valency and Element Types
The question involves matching the concepts of valency, metals, non-metals, and noble gases with their correct definitions. Let's break down each item clearly.
1. Valency
- Valency refers to the combining capacity of an atom.
- It indicates how many electrons an atom can gain, lose, or share to achieve a stable electronic configuration.
2. Metals
- Metals typically lose electrons to become stable.
- They have a tendency to form positive ions (cations) by giving up their outermost electrons.
3. Non-metals
- Non-metals usually gain electrons to achieve stability.
- They tend to form negative ions (anions) by accepting electrons from other atoms.
4. Noble Gases
- Noble gases are known for their stable electronic configuration.
- They have a complete outer shell of electrons, making them largely inert and nonreactive.
Correct Matching
Thus, the correct matches from the options provided are:
- Valency (1) - A (Combining capacity of an atom)
- Metals (2) - C (Loses electron to become stable)
- Non-metals (3) - B (Gains electron to become stable)
- Noble gases (4) - D (They have stable configuration)
This leads us to option 'D' as the correct answer:
1-A, 2-C, 3-B, 4-D
Conclusion
Understanding these concepts helps clarify how different elements interact chemically, highlighting the fundamental principles of chemistry that govern the behavior of atoms in forming compounds.
