Ionic and Covalent Bonds

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when one atom transfers electrons to another atom, resulting in the formation of charged ions that attract each other.

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 to achieve stability.

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 outer shell, achieving a stable electron configuration.

Front

What happens to an atom that loses electrons?

Back

An atom that loses electrons becomes positively charged, forming a cation.

Front

What happens to an atom that gains electrons?

Back

An atom that gains electrons becomes negatively charged, forming an anion.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds occur when electrons are shared unequally between atoms, while nonpolar covalent bonds occur when electrons are shared equally.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together, which can be either covalent or ionic.

Front

What is the significance of electronegativity in bonding?

Back

Electronegativity is a measure of an atom's ability to attract electrons in a bond; it helps determine the type of bond (ionic or covalent) that will form.

Front

What is a Lewis structure?

Back

A Lewis structure is a diagram that represents the bonding between atoms and the lone pairs of electrons in a molecule.

What is the molecular geometry of water (H2O)?

Back

The molecular geometry of water is bent due to the two lone pairs of electrons on the oxygen atom.
