What is a Lewis Dot Structure?

Back

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

What does the term 'valence electrons' refer to?

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 the significance of the octet rule in Lewis Dot Structures?

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.

Front

What is a single bond in terms of electron sharing?

Back

A single bond involves the sharing of one pair of electrons between two atoms.

Front

What is a double bond in terms of electron sharing?

Back

A double bond involves the sharing of two pairs of electrons between two atoms.

Front

What is a triple bond in terms of electron sharing?

Back

A triple bond involves the sharing of three pairs of electrons between two atoms.

Front

What is the difference between ionic and covalent bonding?

Back

Ionic bonding involves the transfer of electrons from one atom to another, while covalent bonding involves the sharing of electrons between atoms.

Front

What happens to an atom when it forms a positive ion?

Back

An atom that forms a positive ion loses one or more electrons.

Front

What happens to an atom when it forms a negative ion?

Back

An atom that forms a negative ion gains one or more electrons.
