Define electron affinity, ionisation potential and atomic radius of Periodic table.
Answers
Answer:
The amount of energy released when an atom in the gaseous state accepts an electron to form an anion. ... As atomic radii increases, electron affinity increases. As nuclear charge increases, electron affinity increases. It decreases down a group and increases across a period.
Answer:
electron affinity
The electron affinity of an atom or molecule is defined as the amount of energy released when an electron is attached to a neutral atom or molecule in the gaseous state to form a negative ion
ionisation potential
Ionization energy is the minimum energy required to remove an electron from an atom or ion in the gas phase. The most common units of ionization energy are kilojoules per mole (kJ/M) or electron volts (eV). Ionization energy exhibits periodicity on the periodic table
atomic radius
The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons
