Multiple Choice

Why do atoms not always share electrons equally in covalent bonds?

• Because atoms have different electronegativities

• Because atoms are always identical

• Because electrons are always shared equally

• Because covalent bonds are always polar

Multiple Choice

What does the term 'electronegativity' refer to in the context of chemical bonding?

• The number of protons in an atom

• The energy required to break a bond

Fill in the Blanks

The symbol

is used to represent a partial charge in chemical bonding.

Multiple Choice

• Polar bonds never create poles in a molecule.

Multiple Choice

Which of the following best describes a nonpolar bond?
