Question

12. Which of the following statements are true? (Use the drop down menus to choose "True" or "False" for each statement. You must get all six statements c Ionization energy values are always positive. Electronegativity is a measure of the relative tendency of an atom to attract the electrons of a chemical bond in which it participates. Non-metals generally have more negative electron affinities than metals The more negative an element's electron affinity is, the more likely that element is to form an anion. Electronegativity values may be either positive or negative Electronegativity is the amount of energy required to add an electron to a neutral atom.

Explanation / Answer

True. - Ionization energy is the energy required to remove an electron from the outermost shell on an atom/ion. Since energy is to be supplied, it is positive. True - It is the definition itself of electronegativity. True - Electron affinity is the energy released when an atom/ion receives an electron. Since non-metals have greater electronegativities and are thus more likely to accept electrons and gain stability from it, it has more negative values of electron affinities. True. - This follows from statement 3. False - Electronegativity is a relative scale of the tendency of an atom to accept an electron, thus it is always positive. The least electronegative atoms would have elctronegativity values close to zero. False - Electronegativity is the relative tendency of atom to accept an electron.
