LT3B.3 Lewis Structures (Honors)

Front

What is a bond?

Back

A bond is a connection between two atoms that allows them to share or transfer electrons.

Front

How many bonds can halogens form?

Back

Halogens can form 1 bond.

Front

What is an octet of electrons?

Back

An octet of electrons refers to a stable arrangement of eight electrons in the outer shell of an atom.

Front

Which element is NOT surrounded by an octet in a Lewis structure?

Back

Hydrogen (H) is not surrounded by an octet.

Front

What does a single line between two atoms represent in a Lewis structure?

Back

A single line represents a shared pair of electrons.

Front

What is a molecule?

Back

A molecule is a substance formed when two or more atoms covalently bond.

Front

How many electrons are shared in a single bond?

Back

2 electrons are shared in a single bond.

Front

What is a covalent bond?

Back

A covalent bond is a type of bond where two atoms share one or more pairs of electrons.

Front

What is the significance of Lewis structures?

Back

Lewis structures help visualize the arrangement of electrons in a molecule.

Front

What do unshared pairs of electrons represent?

Back

Unshared pairs of electrons are pairs that are not involved in bonding and are located on a single atom.
