Lewis Structure/Bonding Practice

Front

What does each line in a Lewis structure represent?

Back

Each line represents a pair of shared electrons (2 electrons).

Front

What should you do if you don't have enough electrons to achieve an octet for each atom in a Lewis structure?

Back

Add a multiple bond to ensure each atom has an octet.

Front

What is the correct Lewis structure for dinitrogen monoxide?

Back

Structure B is the correct Lewis structure for dinitrogen monoxide.

Front

Which pair of elements is most likely to form a covalent bond?

Back

Sulfur (S) and Oxygen (O) are most likely to form a covalent bond.

Front

How many lone pairs does carbon monoxide (CO) have?

Back

Carbon monoxide (CO) has 2 lone pairs.

Front

What is a Lewis structure?

Back

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

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 a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

How do you determine the central atom in a Lewis structure?

Back

The central atom is usually the least electronegative atom or the atom that can form the most bonds.

Front

What is a multiple bond in a Lewis structure?

Back

A multiple bond is a bond that involves more than one pair of shared electrons, such as double or triple bonds.
