Q. The energy required to remove an electron from a neutral isolated gaseous atom and convert it into a positively charged gaseous ion is called _______. (electron affinity, ionisation potential, electronegativity).

Q. When an electron is added to the neutral isolated atom, energy is given out. It is an exothermic process. In this process, monoanion is formed. Electron affinity of an element is defined as the amount of energy liberated when an electron is added to the neutral isolated atom in its ground state. Greater the amount of energy released, greater is the electron affinity. Electron affinity is expressed in terms of

e V a t o m^{- 1}

K c a l

k J m o l^{- 1}

.

Electron affinity of elements depends on which of the following?

Electron affinity of elements depends on which of the following?

Q. Assertion :Electron affinity of noble gas elements is zero. Reason: Electron affinity reflects the ability of an atom to accept an electron. It is the energy change that occurs when an electron is added to a gaseous atom. Atoms with stronger effective nuclear charge have greater electron affinity
