Lewis Dot & Bonding

Front

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.

Front

How many valence electrons does Neon have?

Back

Neon has 8 valence electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have a full set of eight valence electrons.

Front

What is a triple bond?

Back

A triple bond is a type of chemical bond where three pairs of electrons are shared between two atoms.

Front

How many electrons are shared in a double bond?

Back

In a double bond, 4 electrons are shared between two atoms.

Front

What is the tendency of a calcium atom according to the octet rule?

Back

A calcium atom tends to lose 2 electrons.

Front

Which element has the greatest tendency to gain electrons?

Back

Fluorine (F) has the greatest tendency to gain 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 metals generally compare to nonmetals in terms of valence electrons?

Back

Metals generally have fewer valence electrons compared to nonmetals.

Front

What is the significance of the Lewis dot structure in understanding bonding?

Back

Lewis dot structures help visualize how atoms bond and the arrangement of electrons, aiding in predicting molecular shapes and reactivity.
