What is the molecular geometry of PH3?

Back

Trigonal pyramidal.

Front

What does the symbol above F in a Lewis structure indicate?

Back

Electrons are more attracted to F than H.

Front

What type of bond forms when Bromine bonds with Hydrogen?

Back

Polar covalent.

Front

Is H2S a polar or nonpolar molecule?

Back

Polar.

Front

Is the molecule with a symmetrical shape polar or nonpolar?

Back

Non-polar.

Front

Define polarity in chemistry.

Back

Polarity refers to the distribution of electrical charge over the atoms joined by the bond.

Front

What is a polar covalent bond?

Back

A bond where electrons are shared unequally between two atoms, resulting in partial charges.

Front

What is a nonpolar covalent bond?

Back

A bond where electrons are shared equally between two atoms, resulting in no charge separation.

Front

How can you determine if a molecule is polar?

Back

Check for asymmetry in shape and the presence of polar bonds.

Front

What is the significance of electronegativity in determining bond type?

Back

Electronegativity differences between atoms determine whether a bond is ionic, polar covalent, or nonpolar covalent.
