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 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 the significance of Lewis dot structures?

Back

Lewis dot structures visually represent the valence electrons of atoms and how they are shared or transferred in covalent and ionic bonds.

Front

What is the formula for water?

Back

H₂O, which indicates that each water molecule consists of two hydrogen atoms and one oxygen atom.

Front

What is a diatomic molecule?

Back

A diatomic molecule is a molecule composed of two atoms, which can be of the same or different elements, such as O₂ or CO.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they each have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where electrons are shared unequally between two atoms, resulting in a molecule with a slight electrical dipole moment.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of covalent bond where electrons are shared equally between two atoms, resulting in no charge separation.

Front

What is the name of the covalent compound CO₂?

Back

Carbon Dioxide.
