Chemistry - PERIODIC TABLE Question with Solution | TestHub
Electronegativity is defined as the electron-attracting power of an atom towards its nucleus when the atom is covalently bonded in a molecule. Electronegativity of an element is not its inherent property; rather, it depends on the chemical environment in which the atom is present. Measurement of electronegativity can be done by different scales. (Given: )
Identify the correct statement(s).
Options:(select one or more)
Answer:
Solution:
Question Explanation: Evaluate theoretical statements regarding Electronegativity scales.
Concept: Electronegativity scales (Pauling and Mulliken).
Solution: Electronegativity is not an inherent property but depends on the chemical environment, meaning it can vary for the same element in different compounds . Pauling's scale is relative and based on bond energies, while Mulliken's scale is absolute, based on IE and EA. Values on the Mulliken scale are generally 2.8 times larger than on the Pauling scale.
Final Answer: Option : (Statements 1, 2 and 3 are correct.)
