Solution

The correct option is B the nuclear charge
The magnitude of electron affinity depends upon the nuclear charge. The halogens, which are one electron short of a completely filled outer subshell have the greatest attraction for an electron.
The greater the attraction for the electron, the more exothermic the process.

Q. What is electron affinity and how it depends on atomic size, effective nuclear change and screening factor?

Q. Assertion :Manganese has a less favourable electron affinity than its neighbours in either side. Reason: The magnitude of an elements electron affinity depends on the elements valence shell electronic configuration.

Q. The amount of energy released when an atom in the gaseous state accepts an electron to form an anion. factor which affect electron affinity are: atomic size and Nuclear charge. As atomic radii increases, electron affinity increase. As nuclear charge increase, electron affinity increase. it decrease down a group and increases across a period. Explain.

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?

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
