- d and down the group in P.T.​

Answer 1

Answer:

Ionisation energy

ionization energy is the minimum energy required to remove an electron from a gaseous atom in its ground state to form a cation

electron affinity

electron affinity is the amount of energy released when a gaseous atom games an electron to form its anion

Answer 2

Answer:

ionisation energy is the minimum required energy to remove the electron which is loosely bound to the nucleus

the amount energy released when the electron is attached to aneutral atom or molecule in the gaseous state to form a negative ion is called electron affinity

electronegativity is the measure of an atoms ability to attract the shared electrons in the covalent bond...
