What are Lewis Dot Structures?

Back

Lewis Dot Structures are diagrams that represent the valence electrons of atoms within a molecule. They show how electrons are arranged around atoms and how they bond with each other.

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.

What is a single bond?

Back

A single bond is a chemical bond between two atoms involving one pair of shared electrons.

Front

What is a double bond?

Back

A double bond is a chemical bond between two atoms involving two pairs of shared electrons.

What is the significance of valence electrons in bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming bonds with other atoms. They determine the chemical properties and reactivity of the element.

What is the difference between ionic and covalent bonds?

Back

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