Unit 7: Bonding and Nomenclature

Front

What is the definition of ionic bonding?

Back

Ionic bonding is the electrostatic attraction between oppositely charged ions, typically formed when one atom donates an electron to another.

Front

What is the definition of covalent bonding?

Back

Covalent bonding is the sharing of electron pairs between atoms, allowing them to achieve a full outer shell.

Front

What is a polar bond?

Back

A polar bond is a type of covalent bond where electrons are not shared equally between the two atoms, resulting in a dipole moment.

Front

What is the molecular geometry of BF3?

Back

BF3 has a trigonal planar geometry due to the three bonding pairs of electrons and no lone pairs.

Front

What is the molecular geometry of PCl5?

Back

PCl5 has a trigonal bipyramidal geometry due to five bonding pairs of electrons and no lone pairs.

Front

How do you determine if a molecule is polar?

Back

A molecule is polar if it has polar bonds and an asymmetrical shape, leading to a net dipole moment.

Front

What is the significance of lone pairs in molecular geometry?

Back

Lone pairs occupy space and can affect the shape of the molecule, often leading to deviations from ideal bond angles.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is the difference between a molecular formula and an empirical formula?

Back

A molecular formula shows the actual number of atoms of each element in a molecule, while an empirical formula shows the simplest whole-number ratio of the elements.

Front

What is the definition of electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.
