Question

what do you mean by electronegativity and electron gain enthalpy

with examples..

spammers stay away plz​

Answer 1

Electronegativity is defined as the tendency of an atom to attract a shared pair of electron towards itself in a covalent bond . ... ELECTRON GAIN ENTHALPY: It is the energy change that occurs when an electron is added to the outermost shell of a neutral gaseous atom.

Answer 2

Electronegativity: Electronegativity is a chemical property of an atom due to which an atom wants to attract the bond pair electrons towards itself.

EX:- Hydrogen has an electronegativity of 2.0,

‍Electron gain enthalpy: Electron gain enthalpy is a physical measurement of energy which is released from an electron during the addition of an electron is an atom.

EX:- chlorine,iodine
