Correct answer is
Which of the following is affected by stable configuration of an atom?(i)Electronegativity; (ii) Ionization potential and (iii) Electron affinity
Correct answer is
The correct option is C Electron affinity and ionization potential both
We know from electronegativity that Electronegativity may be defined as the tendency of an atom to attract shared pair of electrons of bond towards itself in a covalently bonded molecule.
So, even if an atom has a stable configuration, it does not affect electronegativity.
The factors which affect electronegativity are charge on atom, Effect of substitution. Hybridized state, Atomic radius and Effective nuclear charge.
But we know, Electron Affinity (Ac) term can also be used to measure ability of an atom to gain electron. If energy is released when an electron is added to an atom, the electron affinity is taken as positive, contrary to thermodynamic convention.
Ionization Potential or Ionization Energy
The minimum amount of energy required to remove the most loosely bound electron from an isolated atom in the gaseous state is called ionization energy or enthalpy. Energies or enthalpy. Energies required to remove 2nd - 3rd e− are called successive ionization energy.
And
These two are affected by stable configuration because removing and adding an electron to a stable configuration requires lot of energy because of their stability.
