Question

what is electron gain enthalpy.and electronegativity

Answer 1

Electronegativity Is The Ability Of An Atom in A Chemical Compound Io Attract Shared Electrons Towards Itself. Is Called Elebtronegativity.Fluorine Is The Element With High Electronegativity.Where As Electron Gain Enthalpy Is The Amount Of Energy Released When An Isolated Neutral Gaseous Atom Of The Element Takes Up Extra Electron To Form A Uninegative gaseous Ions Is Known As Electron Gain Enthalpy Or Electron Affinity. The Element With Highest Electron Affinity Is Chlorine With A Value Of -349 K/JMol
