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.

What is the octet rule?

Back

The octet rule states that atoms are generally most stable when they have eight electrons in their valence energy level.

What characterizes an ionic bond?

Back

An ionic bond is formed when one atom transfers electrons to another atom, resulting in the formation of charged ions.

Front

What characterizes a covalent bond?

Back

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

Front

What characterizes a metallic bond?

Back

A metallic bond is formed when electrons are shared among a lattice of metal atoms, creating a 'sea of electrons'.

Front

What is a compound?

Back

A compound is a substance formed when two or more different elements are chemically bonded together.

How do you determine the formula for an ionic compound?

Back

The formula for an ionic compound is determined by the charges of the ions involved, ensuring that the total charge is neutral.

What is a Lewis structure?

Back

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