Electronegativity, metallic and non-metallic characterElectronegativityElectronegativity is the ability of an atom to attract shared electrons in a chemical bond.Measured on the Pauling scale, where fluorine has the highest value (4.0).Electronegativity…
Atomic and ionic radii, ionization energy, electron affinityAtomic and Ionic RadiiThe atomic radius is the distance from the nucleus to the outermost shell of an atom.Atomic radius decreases across a period due to increased nuclear charge, which pulls…
