What is Electron affinity ?
What is Electronegativity ?
What is Ionisation energy ?

[ Need perfect answer, pls ]

Thank you.​

Answer 1

What is Electron affinity :-

Ans : Electron affinity is the energy change that results from adding an electron to a gaseous atom. For example, when a fluorine atom in the gaseous state gains an electron to form F⁻(g), the associated energy change is -328 kJ/mol.

What is Electronegativity :-

Ans : Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group.

What is Ionisation energy :-

Ans : Ionization energy, also called ionization potential, in chemistry and physics, the amount of energy required to remove an electron from an isolated atom or molecule.
