Electronegativity Ionisation and Electron Gain Enthalpies Electronegativity Ionisation and Electron Gain Enthalpies: Ionization Enthalpy (∆iH): Minimum amount of energy required to remove the most loosely bound valence electron from an isolated gaseous atom so as to convert it…

Atomic Properties with Pictorial Representation Atomic Properties with Pictorial Representation: Atomic Properties: The properties such as atomic radius, ionic radius, ionisation energy, electronegativity, electron affinity, and valence, called atomic properties. Atomic Radius: It is defined as the…

Conductivity Molar conductivity and Electrolysis Resistance (R): The electrical resistance is a hindrance to the flow of electrons. Its unit is the ohm (Ω). The resistance of a conductor is directly proportional to the length of the conductor…
