Front

What does VSEPR theory predict?

Back

The shape of molecules.

Front

What type of compounds are formed by ionic bonds?

Back

Ionic compounds are formed by metals and nonmetals.

Front

What is the main principle of the VSEPR model?

Back

Electron pairs around a central atom repel each other and arrange themselves as far apart as possible.

Front

What is the chemical formula for water?

Back

H₂O, which is an example of a molecular formula.

Front

Define ionic bond.

Back

A bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is a molecular formula?

Back

A representation of a molecule that shows the number and type of atoms present.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds have unequal sharing of electrons, while nonpolar covalent bonds have equal sharing.

Front

What is the significance of electronegativity in bonding?

Back

Electronegativity determines how strongly an atom attracts electrons in a bond.

Front

What is a Lewis structure?

Back

A diagram that shows the bonding between atoms and the lone pairs of electrons in a molecule.
