Question

Which of the following statements are true?
A)Non-metals generally have more negative electron affinities than metals.
B)Electronegativity is the amount of energy required to add an electron to a neutral atom.
C)Electronegativity is the tendency of an atom to lessen its electron density when bonded to another atom.
D)Electronegativity is a measurement of the energy released when an atom forms a negative ion.
E)The more negative an element's electron affinity is, the more likely that element is to form an anion.
F)Metals generally have low ionization energies

Explanation / Answer

points (A), (E), (F) are true.

(A) (E)----- Non metals can attain inert gas configuration by gaining electrons , so they release energy while gaining electrons to attain stability.

More negative electron affinity means more energy is released . therefore greater stabilty attained.

(F) ----- Metals have 1 to 3 valence electrons. For them to attain inert gas configuration it is easier to lose electrons rather than to gain them. So they have low ionisation enegies.
