The relative attraction of the nucleus for the electrons in a chemical bond is called _________________?
Correct answer: C. Electro negativity
- A. Ionization energy
- B. Electron affinity
- C. Electro negativity
- D. None of the above
Explanation
Electronegativity is the relative attraction an atom exerts on shared electrons in a chemical bond. The likely mistake is choosing electron affinity, which refers to the energy change when an isolated gaseous atom gains an electron, not its attraction for bonding electrons.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
