Electronegativity means the ability to attract an electron towards itself. high electronegativity means it can attract an electron effectively.
negative electron affinity is described by the amount of energy is released when an electron is added to the neutral atom.
So, if a system has high electronegativity then it will have a high negative electron affinity.
Ionization energy means the minimum amount of energy required to remove an electron from an atom. If the atom is highly electronegative relatively then we need to spare high energy to remove an electron. so the ionization energy will also be high.
ans: large negative electron affinity and a relatively high ionization energy.

The C1-C1 bond energy is 243 kJ/mol. Therefore the breaking of the bond between chlorine atoms should require the absorption of 243 kJ per mote of Cl_2 formed. should require the absorption of486 kJ per mole of Cl_2 formed should result in the release of 243 kJ per mole of Cl_2 formed. should result in the release of 486 Id per mole of Cl_2 form A reactive element with a relatively high electronegativity would be expected to have a relatively...
