Lewis Structures

Front

What is the octet rule?

Back

The octet rule states that most elements need 8 valence electrons to be stable.

Front

How many valence electrons are available for bonding in the sulfate ion (SO₄²⁻)?

Back

The sulfate ion has 32 valence electrons available for bonding.

Front

How many valence electrons does Nitrogen have?

Back

Nitrogen has 5 valence electrons.

Front

What type of bond involves three pairs of shared electrons?

Back

A triple bond involves three pairs of shared electrons.

Front

How many electrons does Hydrogen need in its valence shell to be stable?

Back

Hydrogen needs 2 electrons in its valence shell to be stable.

Front

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.

Front

What is the significance of lone pairs in Lewis structures?

Back

Lone pairs are pairs of valence electrons that are not shared with another atom and can affect the shape and reactivity of the molecule.

Front

What is the maximum number of bonds an atom can form?

Back

The maximum number of bonds an atom can form is determined by the number of valence electrons it has.

Front

What is a single bond?

Back

A single bond is a chemical bond between two atoms involving one pair of shared electrons.

Front

What is a double bond?

Back

A double bond is a chemical bond between two atoms involving two pairs of shared electrons.
