Covalent Bonding

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

What is the Lewis dot structure?

Back

The Lewis dot structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

What is the chemical formula for dinitrogen tetroxide?

Back

N₂O₄

Front

How do covalent compounds differ from ionic compounds?

Back

Covalent compounds share electrons, while ionic compounds transfer electrons.

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

How many valence electrons does fluorine have?

Back

Fluorine has 7 valence electrons.

Front

What happens when atoms do not have enough electrons to complete their octet?

Back

They may form multiple bonds (double or triple bonds) to share more electrons.

Front

What is a single bond in covalent bonding?

Back

A single bond is a covalent bond that involves the sharing of one pair of electrons between two atoms.

Front

What is a double bond in covalent bonding?

Back

A double bond is a covalent bond that involves the sharing of two pairs of electrons between two atoms.

Front

What is a triple bond in covalent bonding?

Back

A triple bond is a covalent bond that involves the sharing of three pairs of electrons between two atoms.
