Question

lets put some of these ideas together. summarize the information you just learned by selecting the three correct statements in the list below.
when two covalently - bonded atoms have the same electronegativity, bond polarity is particularly high.
bond polarity is caused by differences in electronegativity.
bond polarity results in partial positive and partial negative charges on the atoms involved.
partial negative and positive charges do not interact - only full charges do.
with respect to electric charge, likes repel and opposites attract.

Explanation:

1. Bond polarity is indeed caused by differences in electronegativity between bonded atoms. When there is an electronegativity difference, the more electronegative atom attracts the bonding - electrons more, creating partial charges.
2. Bond polarity results in partial positive and partial negative charges on the atoms involved. The more electronegative atom gets a partial negative charge and the less electronegative atom gets a partial positive charge.
3. The fundamental principle of electric charges is that like charges repel and opposite charges attract, which applies to partial charges as well.

Answer:

• Bond polarity is caused by differences in electronegativity.
• Bond polarity results in partial positive and partial negative charges on the atoms involved.
• With respect to electric charge, likes repel and opposites attract.
