8.2 The Nature of Covalent Bonding

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds 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 type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is a coordinate covalent bond?

Back

A coordinate covalent bond is a type of covalent bond in which one atom provides both electrons for the shared pair.

Front

What does a structural formula represent?

Back

A structural formula represents the covalent bonds as dashes and shows the arrangement of atoms in a molecule.

Front

What is bond dissociation energy?

Back

Bond dissociation energy is the energy required to break the bond between two covalently bonded atoms.

Front

Can the octet rule be satisfied in molecules with an even number of valence electrons?

Back

Yes, the octet rule can be satisfied in molecules with an even number of valence electrons.

Front

What is the difference between ionic and covalent bonds?

Back

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

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together by covalent bonds.

Front

What is a single covalent bond?

Back

A single covalent bond is formed when two atoms share one pair of electrons.

Front

What is a double covalent bond?

Back

A double covalent bond is formed when two atoms share two pairs of electrons.
