Bonds Review

Front

What is a bond in chemistry?

Back

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

Front

What are the two main types of chemical bonds?

Back

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 formation of 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 are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons can be determined by the group number of the element in the periodic table.

What is a Lewis structure?

Back

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

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 valence shell, achieving a stable electron configuration.
