Unit 4 Exam Review

Front

What elements generally make an ionic bond?

Back

An ionic bond is formed between a metal and a nonmetal.

Front

London Dispersion forces occur in all molecules, even _________ ones.

Back

London Dispersion forces occur in all molecules, even nonpolar ones.

Front

What is the shape of a molecule with 3 bonded pairs of electrons and 0 lone pairs?

Back

The shape is Trigonal Planar.

Front

What is electronegativity?

Back

Electronegativity is a measurement of the ability of a nucleus to attract bonding electrons.

Front

What is the geometry of a molecule with 3 bonded pairs and 0 lone pairs (AB3)?

Back

The geometry is Trigonal Planar.

Front

Define ionic bond.

Back

An ionic bond is a chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What are London Dispersion forces?

Back

London Dispersion forces are weak intermolecular forces arising from temporary dipoles in molecules.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have a net dipole moment due to uneven distribution of electrons, while nonpolar molecules do not.

Front

What is the significance of electronegativity in chemical bonding?

Back

Electronegativity determines how strongly an atom attracts bonding electrons, influencing bond type and polarity.

Front

What is a molecule with a bent shape?

Back

A bent shape occurs in molecules with 2 bonded pairs and 1 or more lone pairs of electrons.
