Question

11 which of the following periodic trends is most useful in predicting the type of bond that will form between two elements?
options: atomic radius, electronegativity, ionization energy, melting point

Explanation:

To determine the type of bond (ionic, covalent, polar covalent) between two elements, electronegativity is key. The difference in electronegativity values of the two elements dictates bond type: a large difference (usually >1.7) suggests ionic, moderate (0.4 - 1.7) polar covalent, and small (<0.4) non - polar covalent. Atomic radius relates to size trends, ionization energy to electron removal energy, and melting point to physical state, none of which directly predict bond type.

Answer:

B. electronegativity
