Lewis Dot Structures, Covalent and Ionic

Front

What is a Lewis Dot Structure?

Back

A Lewis Dot Structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

Front

What do valence electrons determine?

Back

Valence electrons determine how an atom can bond with other atoms.

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 ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons.

Front

Which type of bond has the largest electronegativity difference?

Back

Ionic bonds have the largest electronegativity difference.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where the electrons are shared unequally between the two atoms, resulting in a partial charge.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of covalent bond where the electrons are shared equally between the two atoms.

Front

How do you determine the shape of a molecule?

Back

The shape of a molecule can be determined using the VSEPR (Valence Shell Electron Pair Repulsion) theory, which states that electron pairs will arrange themselves to minimize repulsion.

Front

What is a resonance structure?

Back

A resonance structure is one of two or more valid Lewis structures for a molecule that cannot be represented accurately by a single Lewis structure.
