Which statement is true? 1. the electronegativity of an atom depends only on the value of the ionization energy of the atom. 2. atoms with high ionization energies and high electron affinities are highly electronegative. 3. atoms with low ionization energies and low electron affinities have high electronegativities. 4. the electronegativity of an atom is defined as 1 2 (electron affinity) of the atom. 5. atoms with high ionization energies and high electron affinities have low electronegativities.

5. Atoms with high ionization energies and high electron affinities have low electronegativities.

Explanation:

Ionization energy is the minimum amount of energy which is required to knock out the loosely bound valence electron from the isolated gaseous atom.

Electron affinity is the amount of energy released when an isolated gaseous atom accepts electron to form the corresponding anion.

Electronegativity is the tendency of an atom in a bond pair to attract the shared pair of electron towards itself.

Low ionization energies as well as low electron affinities mean the atom has low effective nuclear charge, which results in the less attraction of the valence electrons by the atom and thus, low electronegativity.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.
