Lewis Dot Structure Covalent Molecules

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have eight valence electrons, achieving a stable electron configuration.

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.

Front

What is the Lewis dot structure for fluorine (F2)?

Back

The correct Lewis dot structure for F2 shows two fluorine atoms, each with three lone pairs and one shared pair of electrons.

How many double bonds are present in CHCl3?

Back

0

Front

What is the correct Lewis dot structure for chloromethane (CH3Cl)?

Back

The correct structure shows a carbon atom bonded to three hydrogen atoms and one chlorine atom, with no double bonds.

Front

What is the molecular structure of carbon dioxide (CO2)?

Back

The molecular structure of CO2 consists of a carbon atom double bonded to two oxygen atoms.

Front

What are lone pairs in a Lewis dot structure?

Back

Lone pairs are pairs of valence electrons that are not shared with another atom and are typically represented as dots in Lewis structures.

Front

What is the significance of valence electrons in covalent bonding?

Back

Valence electrons are the electrons in the outermost shell of an atom and are crucial for forming bonds with other atoms.

Front

What is a covalent bond?

Back

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