Question

Explain : Electronegativity and electron gain enthalpy. Which of the two can be

measured experimentally​

Answer 1

Explanation:

Electronegativity is defined as the tendency of an element to attract the shared pair of electrons towards itself in a covalent bond. There is no specific unit for electronegativity. Electron gain enthalpy is the energy released when one mole of electron are added to gaseous atoms of an element. It can be negative or positive depending upon whether the electron is added or removed. An element has a constant value of the electron gain enthalpy that can be measured experimentally

Answer 2

Answer:

Electronegativity is the ability of an atom in a compound to attract shared electrons of a covalent bond to itslef. Electron gain enthalpy is the change in the enthalpy accompanying the addition of an electron to gaseous neutral atom forming a gaseous anion.
