Chemical Bonds

Front

What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds.

Front

What are the two main types of chemical bonds?

Back

The two main types of chemical bonds are ionic bonds and covalent bonds.

Front

What is an ionic bond?

Back

An ionic bond is formed when one atom transfers electrons to another atom, resulting in the attraction between positively and negatively charged ions.

Front

What is a covalent bond?

Back

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

Front

What is the octet rule?

Back

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

Front

What is the role of valence electrons in bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming bonds with other atoms.

Front

How do metals typically bond?

Back

Metals typically bond by losing their valence electrons to form positive ions.

Front

How do nonmetals typically bond?

Back

Nonmetals typically bond by gaining or sharing electrons to achieve a full valence shell.

Front

What is a polar covalent bond?

Back

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