Front

What is the significance of molecular shape in chemistry?

Back

It determines the physical and chemical properties of a molecule.

Front

What is a bonding pair of electrons?

Back

A pair of electrons shared between two atoms.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have an uneven distribution of charge, while nonpolar molecules have an even distribution.

Front

What is electronegativity?

Back

The tendency of an atom to attract electrons in a bond.

Front

How does the presence of lone pairs affect molecular geometry?

Back

Lone pairs repel more strongly than bonding pairs, altering the shape.
