In the following question a statement of Assertion (A) followed by a ...
Assertion (A): Smaller the size of an atom greater is the electronegativity.
Reason (R): Electronegativity refers to the tendency of atom so share electrons with other atom.
The given question is related to the concept of electronegativity and the size of atoms. Electronegativity is the measure of an atom's ability to attract electrons towards itself in a chemical bond. It is influenced by several factors, including the size of the atom.
Explanation:
Electronegativity and Atom Size:
- Electronegativity is a property of an atom that depends on its nuclear charge and the distance between the nucleus and the valence electrons.
- Smaller atoms have a higher effective nuclear charge, which means that the positive charge in the nucleus is closer to the valence electrons, resulting in a stronger attraction.
- As a result, smaller atoms have a greater ability to attract electrons towards themselves, leading to higher electronegativity values.
Reasoning:
- The reason provided in the statement is correct. Electronegativity refers to the tendency of an atom to attract or share electrons with another atom in a chemical bond.
- When an atom is small, its valence electrons are closer to the nucleus, resulting in a stronger attraction between the positive nucleus and the negative electrons.
- This increased attraction makes it more likely for the atom to attract or share electrons with another atom, leading to a higher electronegativity.
Conclusion:
- Both the assertion and the reason are true.
- The reason correctly explains why smaller atoms have a greater electronegativity.
- Therefore, the correct option is (a) Both A and R are true and R is the correct explanation of A.
Reason (R): Electronegativity refers to the tendency of atom so share electrons with other atom.
